The weight of a channel is needed to split descriptors between
channels. The weight can depend on maximum rate of channels, maximum
rate of an interface or other reasons. The channel weight is in
percentage and is independent for rx and tx channels.

Add support for forwarding via XDP. Once the eBPF is attached,
driver would allocate & configure a designated transmission queue
meant solely for forwarding packets. Said queue would share the
receive-queue's interrupt line, and would have it's own Tx statistics.
Infrastructure changes required for this [spread-out through the code]:
- Determine the DMA direction of the receive buffers based on the presence
of the eBPF program.
- Turn the sw Tx ring into a union, as regular/XDP queues have different
needs for releasing resources after completion [regular requires the SKB,
XDP requires the transmitted page].

Improve the cacheline usage of both queues by reordering -
This reduces the cachelines required for egress datapath processing
from 3 to 2 and those required by ingress datapath processing by 2.
It also changes a couple of datapath related functions that currently
require either the fastpath or the qede_dev, changing them to be based
on the tx/rx queue instead.

The driver needs to maintain several FW/HW-indices for each one of
its queues. Currently, that mapping is done by the QED where it uses
an rx/tx array of so-called hw-cids, populating them whenever a new
queue is opened and clearing them upon destruction of said queues.
This maintenance is far from ideal - there's no real reason why
QED needs to maintain such a data-structure. It becomes even worse
when considering the fact that the PF's queues and its child VFs' queues
are all mapped into the same data-structure.
As a by-product, the set of parameters an interface needs to supply for
queue APIs is non-trivial, and some of the variables in the API
structures have different meaning depending on their exact place
in the configuration flow.
This patch re-organizes the way L2 queues are configured and maintained.
In short:
- Required parameters for queue init are now well-defined.
- Qed would allocate a queue-cid based on parameters.
Upon initialization success, it would return a handle to caller.
- Queue-handle would be maintained by entity requesting queue-init,
not necessarily qed.
- All further queue-APIs [update, destroy] would use the opaque
handle as reference for the queue instead of various indices.
The possible owners of such handles:
- PF queues [qede] - complete handles based on provided configuration.
- VF queues [qede] - fw-context-less handles, containing only relative
information; Only the PF-side would need the absolute indices
for configuration, so they're omitted here.
- VF queues [qed, PF-side] - complete handles based on VF initialization.

As qede utilizes an internal-reload sequence as result of various
configuration changes, the netif state wouldn't always accurately describe
the status of the configuration.
To compensate, we're storing an internal state of the device, which should
only be accessed under the qede_lock.
This patch fixes and improves several state/lock interactions:
- The internal state should only be checked while locked.
- While holding lock, it's preferable to check state rather than
the netdevice's state.
- The reload sequence is not 'atomic' - unload and subsequent load
are not in the same critical section.
This also add the 'locked' variant for the reload, which would later be
used by XDP - useful in the case where the correct sequence is 'lock,
check state and re-configure if good', instead of allowing the reload
itself to make the decision regarding the configurability of the device.

Driver's NAPI poll is using a long sequence for processing ingress
packets, and it's going to get even longer once we do XDP.
Break down the main loop into a series of sub-functions to allow
better readability of the function.
While we're at it, correct the accounting of the NAPI budget -
currently we're counting only packets passed to the stack against
the budget, even in case those are actually aggregations.
After refactoring every CQE processed would be counted against the budget.

The chain structure and functions are widely used by the qed* modules,
both for configuration and datapath.
E.g., qede's Tx has one such chain and its Rx has two.
Currently, the strucutre's fields which are required for datapath
related functions [produce/consume] are intertwined with fields which
are required only for configuration purposes [init/destroy/etc.].
This patch re-arranges the chain structure so that all the fields which
are required for datapath usage could reside in a single cacheline instead
of the two which are required today.

Driver needs to maintain a structure per-each concurrent possible
open aggregation, but the structure storing that metadata is far from
being optimized - biggest waste in it is that there are 2 buffer metadata,
one for a replacement buffer when the aggregation begins and the other for
holding the first aggregation's buffer after it begins [as firmware might
still update it]. Those 2 can safely be united into a single metadata
structure.
struct qede_agg_info changes the following:
/* size: 120, cachelines: 2, members: 9 */
/* sum members: 114, holes: 1, sum holes: 4 */

Rationale: The differences between Falcon and Siena are in many ways larger
than those between Siena and EF10 (despite Siena being nominally "Falcon-
architecture"); for instance, Falcon has no MCPU, so there is no MCDI.
Removing Falcon support from the sfc driver should simplify the latter,
and avoid the possibility of Falcon support being broken by changes to sfc
(which are rarely if ever tested on Falcon, it being end-of-lifed hardware).
The sfc-falcon driver created in this changeset is essentially a copy of the
sfc driver, but with Siena- and EF10-specific code, including MCDI, removed
and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000-
series") to avoid collisions when both drivers are built-in.
This changeset removes Falcon from the sfc driver's PCI ID table; then in
sfc I've removed obvious Falcon-related code: I removed the Falcon NIC
functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything
that referenced them.
Also, increment minor version of both drivers (to 4.1).
For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs
doesn't cause Falcon support to disappear; but that should be undone at
some point in the future.

If device_release_driver(&phydev->mdio.dev) is called, it releases all
resources belonging to the PHY device. Hence the subsequent call to
phy_led_triggers_unregister() will access already freed memory when
unregistering the LEDs.
Move the call to phy_led_triggers_unregister() before the possible call
to device_release_driver() to fix this.

When a hardware issue happened as described by inline comments, the register
write pattern looks like the following:
<write ~MACB_BIT(RE)>
+ wmb();
<write MACB_BIT(RE)>
There might be a memory barrier between these two write operations, so add wmb
to ensure an flip from 0 to 1 for NCR.

On macb only (not gem), when a RX queue corruption was detected from
macb_rx(), the RX queue was reset: during this process the RX ring
buffer descriptor was initialized by macb_init_rx_ring() but we forgot
to also set bp->rx_tail to 0.
Indeed, when processing the received frames, bp->rx_tail provides the
macb driver with the index in the RX ring buffer of the next buffer to
process. So when the whole ring buffer is reset we must also reset
bp->rx_tail so the driver is synchronized again with the hardware.
Since macb_init_rx_ring() is called from many locations, currently from
macb_rx() and macb_init_rings(), we'd rather add the "bp->rx_tail = 0;"
line inside macb_init_rx_ring() than add the very same line after each
call of this function.
Without this fix, the rx queue is not reset properly to recover from
queue corruption and connection drop may occur.

This patch allows rx/tx bytes/packets counters being folded at the

We now can fetch stats every 1 ms if we want to check NIC behavior

Marvell Wifi PCIe modules don't always behave nicely for PCIe power
management when their firmware hasn't been loaded, particularly after
suspending the PCIe link one or more times. When this happens, we might
end up spinning forever in this status-polling tight loop. Let's make
this less tight by adding a timeout and by sleeping a bit in between
reads, as we do with the other similar loops.
This prevents us from hogging a CPU even in such pathological cases, and
allows the FW initialization to just fail gracefully instead.
I chose the same polling parameters as the earlier loop in this
function, and empirically, I found that this loop never makes it more
than about 12 cycles in a sane FW init sequence. I had no official
information on the actual intended latency for this portion of the
download.

Current implementation saves the ETS settings from user in
a temporal soft copy and returns this settings when user
queries the ETS settings.
With the new DCBX firmware, the ETS settings can be changed
by firmware when the DCBX is in firmware controlled mode. Therefore,
user will obtain wrong values from the temporal soft copy.
Solution:
1. Read the ETS settings directly from firmware.
2. For tc_tsa:
a. Initialize tc_tsa to vendor IEEE_8021QAZ_TSA_VENDOR at netdev
creation.
b. When reading ETS setting from FW, if the traffic class bandwidth
is less than 100, set tc_tsa to IEEE_8021QAZ_TSA_ETS. This
implementation solves the scenarios when the DCBX is in FW control
and willing bit is on which means the ETS setting is dictated
by remote switch.
Also check ETS capability where needed.

Add DCBX CEE API interface for ConnectX-4. Configurations are stored in
a temporary structure and are applied to the card's firmware when
the CEE's setall callback function is called.
Note:
priority group in CEE is equivalent to traffic class in ConnectX-4
hardware spec.
bw allocation per priority in CEE is not supported because ConnectX-4
only supports bw allocation per traffic class.
user priority in CEE does not have an equivalent term in ConnectX-4.
Therefore, user priority to priority mapping in CEE is not supported.

We use single queue even if multiqueue is enabled and let admin to
enable it through ethtool later. This is used to avoid possible
regression (small packet TCP stream transmission). But looks like an
overkill since:
- single queue user can disable multiqueue when launching qemu
- brings extra troubles for the management since it needs extra admin
tool in guest to enable multiqueue
- multiqueue performs much better than single queue in most of the
cases
So this patch enables multiqueue by default: if #queues is less than or
equal to #vcpu, enable as much as queue pairs; if #queues is greater
than #vcpu, enable #vcpu queue pairs.

The old logic always enabled the TX-delay when the phy-mode was set to
PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the
PHY driver to enable the RX and/or TX delays:
- PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the
PHY (if required, the MAC should add the delays in this case)
- PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY
(currently not supported by RTL8211F)
With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID
and PHY_INTERFACE_MODE_RGMII_TXID.
Additionally we now explicity disable the TX-delay, which seems to be
enabled automatically after a hard-reset of the PHY (by triggering it's
reset pin) to get a consistent state (as defined by the phy-mode).
This fixes a compatibility problem with some SoCs where the TX-delay was
also added by the MAC. With the TX-delay being applied twice the TX
clock was off and TX traffic was broken or very slow (<10Mbit/s) on
1000Mbit/s links.

This patch depends on commit d8d2635419 ("ptp: Introduce a high
resolution frequency adjustment method.")
The gianfar devices offer a frequency resolution of about 0.46 ppb
(depends on actual value of tmr_add, for the calculation assumed
0x80000000). This patch lets users of the device benefit from the increased
frequency resolution when tuning the clock. Thanks to the rounding the
maximum error between the requested frequency and the applied frequency
will then be about 0.23 ppb.
Tested on a v3.3.8 kernel on a real gianfar device. Verified compilation
on net-next (currently at v4.9-rc5).

Configure policers and connect them to trap groups.
While many trap groups share policer's configuration they don't share
the actual policer because each trap group represents a different
flow / protocol and we don't want one of them to be able to exceed its
rate on behalf of another.
For example, if STP and LLDP gets to send 128 packets/sec each, if we
put them in one 256 packets/sec policer, one can send 200 packets while
the other only 50.
Note that IP2ME covers lots of flows, so it's limit is set to match the
cpu ability to handle data.

Trap groups can be used to control traps priority, both in terms of
which trap "wins" if a packet matches two traps (priority) and in terms
of packets from which trap group will be scheduled to the cpu first (tc).
They can also be used to set rate limiters (policers) on them (will be
added in the next patches).
Currently, we support two trap groups. In Spectrum we want a better
resolution, so every protocol / flow will have a different trap group,
so we can control its parameters separately. Once the policers will be
implemented, it will also allow us limit the rate of each protocol by
itself.
This patch change the trap group list to include:
* the emad trap group, which is shared for all the devices.
* Switchx2's trap groups, which are a copy of the current trap groups.
* Spectrum's new trap groups, in order to match the above guidelines.
(Switchib is using only the emad trap group, so it require no changes).
This patch also includes new configuration for Spectrum's trap groups,
with primary priority order within them.

Trap groups have many options which we currently set to default values.
In the next patches we will use many of them with non-default values.
Some of these options have no default value, so this patch sets them as
params for the trap group set function. Others almost always use the same
values, so the set function will use this default values. In the rare cases
when they will need to be with other values, these values can be set
directly (using the macros for fields in registers).
Parameters without default value:
TC - the traffic class for packets that hit this trap group.
(old default is the max tc)
priority - if one packet hits multiple trap groups, the group with the
higher priority will "catch" it. (old default is 0)
policer - limit rate policer (old default is disabled)
Default parameters:
swid - switch id, relevant for the emad trap only, ignored on Spectrum.
(new default is 0)
rdq - CPU receive descriptor queue (new default is identical to trap
group id)

The report is valid: doing the math in this function, with an input value
N=63 the variable s16tableIndex gets a value of 31. This value is used as
an index in the array log_table with 32 entries. But the next line is:
s16errorApproximation = (s16) qm_mulu16(u16offset,
(u16) (log_table[s16tableIndex + 1] -
log_table[s16tableIndex]));
With s16tableIndex + 1 we are trying an out-of-bounds access to the array.
The log_table array provides log2 values in q.15 format and the above
statement tries an error approximation with the next value. To fix this
issue add the next value to the array and update the comment accordingly.

The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and

In addition it also seems prone to issues when setting REG_RF_CTRL to

A device running without RX package aggregation could return more data

Indicate hardware (or firmware) supports that CQM packet-loss report
will be generated based on station kickout algorithm. As of now mac80211
tracks connection loss by missing msdu counts (50) whereas ath10k
firmware tracks them by missing ppdus (+ BAR tries). While firmware is
trying to adapt its rate table, mac80211 might send out low_ack event to
hostapd. This is causing frequent connect and disconnect iteration under
noisy environment or when station is roaming around.

ath.git patches for 4.10. Major changes:
ath9k
* add device tree bindings
* switch to use mac80211 intermediate software queues to reduce
latency and fix bufferbloat
All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Both of these drivers won't work on 64-bit architectures unless they
are redesigned, since they store a virtual address pointer in a 32-bit
field of the descriptors:
drivers/net/ethernet/marvell/mvneta_bm.c: In function 'mvneta_bm_construct':
drivers/net/ethernet/marvell/mvneta_bm.c:103:16: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

drivers/net/ethernet/marvell/mvpp2.c:2563:32: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
This limits the COMPILE_TEST option for the two drivers again to
only build them on 32-bit. This seems nicer than shutting up the
warnings, in case we ever actually want to use them on 64-bit,
as the warnings indicate which parts of the driver are currently
broken there.

Current geneve implementation has two separate cases to handle.
1. netdev xmit
2. LWT xmit.
In case of netdev, geneve configuration is stored in various
struct geneve_dev members. For example geneve_addr, ttl, tos,
label, flags, dst_cache, etc. For LWT ip_tunnel_info is passed
to the device in ip_tunnel_info.
Following patch uses ip_tunnel_info struct to store almost all
of configuration of a geneve netdevice. This allows us to unify
most of geneve driver code around ip_tunnel_info struct.
This dramatically simplify geneve code, since it does not
need to handle two different configuration cases. Removes
duplicate code, single code path can handle either type
of geneve devices.

While stressing a 40Gbit mlx4 NIC with busy polling, I found false

This patch brings an additional 7 % performance improvement in UDP_RR
workload.
1) If we received no frame during one mlx4_en_process_rx_cq()
invocation, no need to call mlx4_cq_set_ci() and/or dirty ring->cons
2) Do not refill rx buffers if we have plenty of them.
This avoids false sharing and allows some bulk/batch optimizations.
Page allocator and its locks will thank us.
Finally, mlx4_en_poll_rx_cq() should not return 0 if it determined
cpu handling NIC IRQ should be changed. We should return budget-1
instead, to not fool net_rx_action() and its netdev_budget.

There are multiple issues in mlx5e_xdp_set():
1) The batched bpf_prog_add() is currently not checked for errors. When
doing so, it should be done at an earlier point in time to makes sure
that we cannot fail anymore at the time we want to set the program for
each channel. The batched refs short-cut can only be performed when we
don't need to perform a reset for changing the rq type and the device
was in opened state. In case the device was not in opened state, then
the next mlx5e_open_locked() will aquire the refs from the control prog
via mlx5e_create_rq(), same when we need to perform a reset.
2) When swapping the priv->xdp_prog, then no extra reference count must be
taken since we got that from call path via dev_change_xdp_fd() already.
Otherwise, we'd never be able to release the program. Also, bpf_prog_add()
without checking the return code could fail.

It's possible for the FW init sequence to fail, which will trigger a
device cleanup sequence in mwifiex_fw_dpc(). This sequence can race with
device suspend() or remove() (e.g., reboot or unbind), and can trigger
use-after-free issues. Currently, this driver attempts (poorly) to
synchronize remove() using a semaphore, but it doesn't protect some of
the critical sections properly. Particularly, we grab a pointer to the
adapter struct (card->adapter) without checking if it's being freed or
not. We later do a NULL check on the adapter, but that doesn't work if
the adapter was freed.
Also note that the PCIe interface driver doesn't ever set card->adapter
to NULL, so even if we get the synchronization right, we still might try
to redo the cleanup in ->remove(), even if the FW init failure sequence
already did it.
This patch replaces the static semaphore with a per-device completion
struct, and uses that completion to synchronize the remove() thread with
the mwifiex_fw_dpc(). A future patch will utilize this completion to
synchronize the suspend() thread as well.

Merge tag 'v4.9-rc4' into sound
Bring in -rc4 patches so I can successfully merge the sound doc changes.
sunbmac uses '__u32' for dma handle while invoking kernel DMA APIs,
instead of using dma_addr_t. This hasn't caused any 'incompatible
pointer type' warning on SPARC because until now dma_addr_t is of
type u32. However, recent changes in SPARC ATU (iommu) enables 64bit
DMA and therefore dma_addr_t becomes of type u64. This makes
'incompatible pointer type' warnings inevitable.
e.g.
drivers/net/ethernet/sun/sunbmac.c: In function ‘bigmac_ether_init’:

* UCC_GETH which depends on PowerPC cpm.h header (which could be moved

* GIANFAR needs to depend on HAS_DMA to fix linking failures on some
architectures (like m32r)
We need to fix an unmet dependency to get there though:

Also do that if the TSO handler fails with EINVAL for any other reason.

Add support for FATSOv2 to the driver. FATSOv2 offloads far more of the task
of TCP segmentation to the firmware, such that we now just pass a single
super-packet to the NIC. This means TSO has a great deal in common with a
normal DMA transmit, apart from adding a couple of option descriptors.
NIC-specific checks have been moved off the fast path and in to
initialisation where possible.
This also moves FATSOv1/SWTSO to a new file (tx_tso.c). The end of transmit
and some error handling is now outside TSO, since it is common with other
code.

Make struct pernet_operations::id unsigned.
There are 2 reasons to do so:
1)
This field is really an index into an zero based array and
thus is unsigned entity. Using negative value is out-of-bound
access by definition.
2)
On x86_64 unsigned 32-bit data which are mixed with pointers
via array indexing or offsets added or subtracted to pointers
are preffered to signed 32-bit data.
"int" being used as an array index needs to be sign-extended
to 64-bit before being used.
void f(long *p, int i)
{
g(p[i]);
}
roughly translates to
movsx rsi, esi
mov rdi, [rsi+...]
call g
MOVSX is 3 byte instruction which isn't necessary if the variable is
unsigned because x86_64 is zero extending by default.
Now, there is net_generic() function which, you guessed it right, uses
"int" as an array index:
static inline void *net_generic(const struct net *net, int id)
{
...
ptr = ng->ptr[id - 1];
...
}
And this function is used a lot, so those sign extensions add up.
Patch snipes ~1730 bytes on allyesconfig kernel (without all junk
messing with code generation):
add/remove: 0/0 grow/shrink: 70/598 up/down: 396/-2126 (-1730)
Unfortunately some functions actually grow bigger.
This is a semmingly random artefact of code generation with register
allocator being used differently. gcc decides that some variable
needs to live in new r8+ registers and every access now requires REX
prefix. Or it is shifted into r12, so [r12+0] addressing mode has to be
used which is longer than [r8]
However, overall balance is in negative direction:

The cleanup_if() callback is the inverse of init_if(). We allocate our
'card' interface structure in the probe() function, but we free it in
cleanup_if(). That gives a few problems:
(a) we leak this memory if probe() fails before we reach init_if()
(b) we can't safely utilize 'card' after cleanup_if() -- namely, in
remove() or suspend(), both of which might race with the cleanup
paths in our asynchronous FW initialization path
Solution: just use devm_kzalloc(), which will free this structure
properly when the device is removed -- and drop the set_drvdata(...,
NULL), since the driver core does this for us. This also removes the
temptation to use drvdata == NULL as a hack for checking if the device
has been "cleaned up."
I *do* leave the set_drvdata(..., NULL) for the hacky SDIO
mwifiex_recreate_adapter(), since the device core won't be able to clear
that one for us.

The stmmac driver use lots of pr_xxx functions to print information.
This is bad since we cannot know which device logs the information.
(moreover if two stmmac device are present)
Furthermore, it seems that it assumes wrongly that all logs will always
be subsequent by using a dev_xxx then some indented pr_xxx like this:
kernel: sun7i-dwmac 1c50000.ethernet: no reset control found
kernel: Ring mode enabled
kernel: No HW DMA feature register supported
kernel: Normal descriptors
kernel: TX Checksum insertion supported
So this patch replace all pr_xxx by their netdev_xxx counterpart.
Excepts for some printing where netdev "cause" unpretty output like:
sun7i-dwmac 1c50000.ethernet (unnamed net_device) (uninitialized): no reset control found
In those case, I keep dev_xxx.
In the same time I remove some "stmmac:" print since
this will be a duplicate with that dev_xxx displays.

On x86, the cw1200 driver produces a rather silly warning about the
possible use of the 'ret' variable without an initialization
presumably after being confused by the architecture specific definition
of WARN_ON:
drivers/net/wireless/st/cw1200/wsm.c: In function ‘wsm_handle_rx’:
drivers/net/wireless/st/cw1200/wsm.c:1457:9: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
We have already checked that 'count' is larger than 0 here, so
we know that 'ret' is initialized. Changing the 'for' loop
into do/while also makes this clear to the compiler.

The hostap_80211_rx() function is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:
drivers/net/wireless/intersil/hostap/hostap_80211_rx.c: In function ‘hostap_80211_rx’:
arch/x86/include/asm/string_32.h:77:14: warning: ‘src’ may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/wireless/intel/ipw2x00/libipw_rx.c: In function ‘libipw_rx’:
arch/x86/include/asm/string_32.h:77:14: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
arch/x86/include/asm/string_32.h:78:22: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.
The same code is duplicated several times in the kernel, so this
patch uses the same workaround for all copies. The exact configuration
was hit only very rarely in randconfig builds and I only saw it
in three drivers, but I assume that all of them are potentially
affected, and it's better to keep the code consistent.

We currently have a fundamental problem in how we treat the CPU port and
its VLAN membership. As soon as a second VLAN is configured to be
untagged, the CPU automatically becomes untagged for that VLAN as well,
and yet, we don't gracefully make sure that the CPU becomes tagged in
the other VLANs it could be a member of. This results in only one VLAN
being effectively usable from the CPU's perspective.
Instead of having some pretty complex logic which tries to maintain the
CPU port's default VLAN and its untagged properties, just do something
very simple which consists in neither altering the CPU port's PVID
settings, nor its untagged settings:
- whenever a VLAN is added, the CPU is automatically a member of this
VLAN group, as a tagged member
- PVID settings for downstream ports do not alter the CPU port's PVID
since it now is part of all VLANs in the system
This means that a typical example where e.g: LAN ports are in VLAN1, and
WAN port is in VLAN2, now require having two VLAN interfaces for the
host to properly terminate and send traffic from/to.

for getting HW transmit completion notification. This dummy
SQE has 'dont_send' set and HW drops the pkt pointed to in this
thus Tx drop counter increases. This patch fixes this by subtracting
SW tx tso counter from HW Tx drop counter for actual packet drop counter.

In order to break the hard dependency between the PTP clock subsystem and
ethernet drivers capable of being clock providers, this patch provides
simple PTP stub functions to allow linkage of those drivers into the
kernel even when the PTP subsystem is configured out. Drivers must be
ready to accept NULL from ptp_clock_register() in that case.
And to make it possible for PTP to be configured out, the select statement
in those driver's Kconfig menu entries is converted to the new "imply"
statement. This way the PTP subsystem may have Kconfig dependencies of
its own, such as POSIX_TIMERS, without having to make those ethernet
drivers unavailable if POSIX timers are cconfigured out. And when support
for POSIX timers is selected again then the default config option for PTP
clock support will automatically be adjusted accordingly.
The pch_gbe driver is a bit special as it relies on extra code in
drivers/ptp/ptp_pch.c. Therefore we let the make process descend into
drivers/ptp/ even if PTP_1588_CLOCK is unselected.

We must change the poll function because with multiple queues it is possible

Add new functions to allocate and free the alx_napi structures and use them
in __alx_open and __alx_stop. We only allocate one of these structures for
now, as the rest of the driver is not yet ready for multiple queues.
We switch over the setup of the interrupt mask and the call to netif_napi_add
to the new function because we must adjust these later on a per queue basis.

The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand
it is used to move actual packet data off the wire. This will be in
wire-format and accepted as such by higher layers such as IP. Therefore
it is correctly read as-is (i.e. raw) using readsl.
On the other hand it provides metadata about incoming transfers to the
driver such as length and checksum validation status. This data is
little-endian, always and it is interpreted by the driver. Therefore it
needs to be swapped to CPU endianness to make sense to the driver. This
is already done for the "receive header" but not rxhdr.
Read rxhdr using readl in order for sun4i-emac to work correctly when
running a big-endian kernel.

This switches ath9k over to using the mac80211 intermediate software
queueing mechanism for data packets. It removes the queueing inside the
driver, except for the retry queue, and instead pulls from mac80211 when
a packet is needed. The retry queue is used to store a packet that was
pulled but can't be sent immediately.
The old code path in ath_tx_start that would queue packets has been
removed completely, as has the qlen limit tunables (since there's no
longer a queue in the driver to limit).
The mac80211 intermediate software queues offer significant latency
reductions, and this patch allows ath9k to realise them. The exact gains
from this varies with the test scenario, but in an access point scenario
we have seen latency reductions ranging from 1/3 to as much as an order
of magnitude. We also achieve slightly better aggregation.
Median latency (ping) figures with this patch applied at the access point,
with two high-rate stations and one low-rate station (HT20 5Ghz), running
a Flent rtt_fair_var_up test with one TCP flow and one ping flow going to
each station:
Fast station Slow station
Default pfifo_fast qdisc: 430.4 ms 638.7 ms
fq_codel qdisc on iface: 35.5 ms 211.8 ms
This patch set: 22.4 ms 38.2 ms

The active_high LED of my Wistron DNMA-92 is still being recognized as
active_low on 4.7.6 mainline. When I was preparing my former commit
0f9edcdd88 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92
cards.") to fix that I must have somehow messed up with testing, because
I tested the final version of that patch before sending it, and it was
apparently working; but now it is not working on 4.7.6 mainline.
I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the
PCI_VDEVICE section for 0x0029; but then I moved the former below the
latter after seeing how 0x002A sections were sorted in the file.
This turned out to be wrong: if a generic PCI_VDEVICE entry (that has
both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more
specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will
match first and will be used.
With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6.
While I'm at it, let's fix 0x002A too by also moving its generic definition
below its specific ones.

Since commit b45f64d16d ("mlxsw: spectrum_router: Use FIB notifications

During module removal, FIBs of the second type are removed following
NETDEV_UNREGISTER events sent. The other FIBs are still present in both
the driver's cache and the device's table.
Fix this by iterating over all the FIB tables in the device and flush
them. There's no need to take locks, as we're the only writer.

Commit 52f95bbfcf ("stmmac: fix adjust link call in case of a switch

therefore invoking the adjust_link callback more than once, since this
is a fixed PHY and link events won't be generated.
This works fine the first time, because we start with phydev->irq =
PHY_POLL, so we call adjust_link, then we set phydev->irq =
PHY_IGNORE_INTERRUPT and we stop polling the PHY.
Now, if we called ndo_close(), which calls both phy_stop() and does an
explicit netif_carrier_off(), we end up with a link down. Upon calling
ndo_open() again, despite starting the PHY state machine, we have
PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the
link is permanently down.

efx_copy_channel() doesn't correctly clear the napi_hash related state.
This means that when napi_hash_add is called for that channel nothing is
done, and we are left with a copy of the napi_hash_node from the old
channel. When we later call napi_hash_del() on this channel we have a
stale napi_hash_node.
Corruption is only seen when there are multiple entries in one of the
napi_hash lists. This is made more likely by having a very large number
of channels. Testing was carried out with 512 channels - 32 channels on
each of 16 ports.
This failure typically appears as protection faults within napi_by_id()
or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring
sizes are changed (ethtool -G).

The device's neighbour table is periodically dumped in order to update
the kernel about active neighbours. A single dump session may span
multiple queries, until the response carries less records than requested
or when a record (can contain up to four neighbour entries) is not full.
Current code stops the session when the number of returned records is
zero, which can result in infinite loop in case of high packet rate.
Fix this by stopping the session according to the above logic.

Update the reading of the Tx timestamp to account for a hardware issue
on how the fields and interrupt are cleared. The "seconds" portion of
the timestamp should be read first, followed by the "nanoseconds" portion.
Reading the "nanoseconds" portion should clear the timestamp data and the
interrupt. Because of an issue with the hardware this order is reversed
and reading the "seconds" portion actually clears the timestamp. The code
currently follows this workaround, but to guard against future versions
where this is fixed add a field to the version data to indicate if the

Commit 67f8b1dcb9 ("net/mlx4_en: Refactor the XDP forwarding rings

in the error path when mlx4_en_try_alloc_resources() is failing from
mlx4_xdp_set().
We previously took bpf_prog_add(prog, priv->rx_ring_num - 1), that we
need to release again. Earlier in the call path, dev_change_xdp_fd()
itself holds a reference to the prog as well (hence the '- 1' in the
bpf_prog_add()), so a simple atomic_sub() is safe to use here. When
an error is propagated, then bpf_prog_put() is called eventually from
dev_change_xdp_fd()

__neigh_create function works in a different way than assumed.
It passes "n" as a parameter to ndo_neigh_construct. But this "n" might
be destroyed right away before __neigh_create() returns in case there is
already another neighbour struct in the hashtable with the same dev and
primary key. That is not expected by mlxsw_sp_router_neigh_construct()
and the stored "n" points to freed memory, eventually leading to crash.
Fix this by doing tight 1:1 coupling between neighbour struct and
internal driver neigh_entry. That allows to narrow down the key in
internal driver hashtable to do lookups by "n" only.

In mlx5 HW, encapsulation is offloaded by the steering rule having
index into an encapsulation table containing the entire set of headers
to be added by the HW. The driver sets these headers in a buffer when we
are offloading the action.
The code maintains mlx5_encap_entry for each encap header it has
encountered when attempted to offload TC tunnel set action.
This entry maintains a linked list of all the flows sharing the same
encap header, when the last flow is removed from the list the encap
entry is removed.
The actual encap_header is allocated by the driver in the hardware only
if we have layer two neighbour info when the encap entry is created.
While the flow is in the driver, the driver holds a reference on the
neighbour.
When a new flow with encap action is inserted, the code first checks if
the required encap entry exists according to the tunnel set parameters.
If it does the encap is shared, otherwise a new mlx5_encap_entry is
created.
TC action parsing implementation in the driver assumes that tunnel set
action is provided in the same order set by the user, e.g before the
mirred_redirect action.

The smsc911c driver puts its device into low power state when entering
system suspend. Although it doesn't update the device's runtime PM status
to RPM_SUSPENDED, which causes problems for a parent device.
In particular, when the runtime PM status of the parent is requested to be
updated to RPM_SUSPENDED, the runtime PM core prevent this, because it's
forbidden to runtime suspend a device, which has an active child.
Fix this by updating the runtime PM status of the smsc911x device to
RPM_SUSPENDED during system suspend. In system resume, let's reverse that
action by runtime resuming the device and thus also the parent.

It involves three threads. suspend handler, interrupt handler, interrupt
processing in main work queue.
1) Enter suspend handler
2) Download HS_CFG command
3) Response from firmware for HS_CFG
4) Suspend thread waits until handshake completes(i.e hs_activate becomes
true)
5) SLEEP from firmware
6) SLEEP confirm downloaded to firmware.
7) SLEEP confirm response from firmware
8) Driver processes SLEEP confirm response and set hs_activate to wake up
suspend thread
9) Exit suspend handler
10) Read sleep cookie in loop and wait until it indicates firmware is
sleep.
11) After processing SLEEP confirm response, we are at the end of interrupt
processing routine. Recheck if there are interrupts received while we were
processing them.
During suspend-resume stress test, it's been observed that we may end up

This patch solves the problem with below changes.

b) Skip 11 if hs_activated is true. SLEEP confirm response
is the last interrupt from firmware. No need to recheck for
pending interrupts.
