abc5a021ba bnx2x: Support PF <-> VF Bulletin Board
The PF <-> VF Bulletin Board is a simple interface between the
PF and the VF. The main reason for the Bulletin Board is to allow
the PF to be the initiator. The VF publishes at 'acquire' stage
the GPA of a Bulletin Board structure it has allocated. The PF notes
this GPA in the VF database. The VF samples the Bulletin Board
periodically for new messages. The latest version of the BB is always
used.

f1929b016c bnx2x: Support of PF driver of a VF release request
The 'release' request is the opposite of the 'acquire' request.
At release, all the resources allocated to the VF are reclaimed.
The release flow applies the close flow if applicable.
Note that there are actually two types of release:
1. The VF has been removed, and so issued a 'release' request
over the VF <-> PF Channel.
2. The PF is going down and so has to release all of it's VFs.

67c431a5f2 bnx2x: Support statistics collection for VFs by the PF
Statistics are collected by the PF driver. The collection is
performed via a query sent to the device which is basically an array
of 3-tuples of the form (statistics client, function, DMAE address).
In this patch the PF driver adds to the query, on top of the
statistics clients it is maintaining for itself (rss queues, storage,
etc), the 3-tuples for the VFs it is maintaining. The addresses used
are the GPAs of the statistics buffers supplied by the VF in the
init message on the VF <-> PF channel. The function parameter
ensures that the iommu will translate the GPA to the correct physical
address.

381ac16b10 bnx2x: Support ndo_set_rxmode in VF driver
The VF driver uses the 'q_filter' request in the VF <-> PF channel to
have the PF configure the requested rxmode to device. ndo_set_rxmode
is called under bottom half lock, so sleeping until the response
arrives over the VF <-> PF channel is out of the question. For this reason
the VF driver returns from the ndo after scheduling a work item, which
in turn processes the rx mode request and adds the classification
information through the VF <-> PF channel accordingly.

5be78ee924 RDMA/cxgb4: Fix LE hash collision bug for active open connection
It enables establishing active open connection using fw_ofld_connection work
request when cpl_act_open_rpl says TCAM full error which may be because
of LE hash collision. Current support is only for IPv4 active open connections.

Sets ntuple bits in active open requests. For T4 firmware greater than 1.4.10.0
ntuple bits are required to be set.

Adds nocong and enable_ecn module parameter options.

4945106d21 ksz884x: fix receive polling race condition
The ksz884x driver does receive processing in a custom tasklet, and
seems to be assuming that since it takes its private interface spinlock
with spin_lock_irq(), it won't be running concurrently with its own
interrupt handler, as it cannot be preempted by it, but since its
interrupt handler doesn't do any locking whatsoever, the receive
processing tasklet and interrupt handler can end up running concurrently
on different CPUs.

As a result of this, the ksz884x receive path ends up locking up fairly
easily, when the receive processing tasklet's reenabling of receive
interrupts (due to it being done with polling the receive ring) races
with the interrupt handler's disabling of receive interrupts (due to a
new receive interrupt coming in) resulting in the receive interrupt
being masked but the receive processing tasklet not being scheduled.

Fix this by making the ksz884x interrupt handler take its private
interface spinlock.  This requires upgrading the spin_lock() in the
transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ
handler can preempt transmit cleanup and deadlock the system, but
with those two changes, no more receive lockups have been observed.

7b8157bedc mlx4_core: Adjustments to Flow Steering activation logic for SR-IOV
Separate flow steering capability detection from the decision to activate.

For the master (and for native), detect the flow steering capability
in mlx4_dev_cap, but activate the appropriate steering type in a new
function choose_flow_steering() based on detected data.

For VFs, activate flow steering based on what was actually activated
by the master, where that info is obtained via QUERY_HCA. This fixes
the current VF detection which is wrongly based on QUERY_DEV_CAP.

Also, for SR-IOV mode, if flow steering may be activated, do so only
if the max number of QPs per rule is sufficient to satisfy one
subscription per VF.  If not, fall back to B0 mode. This is needed to
serve registrations done by L2 network drivers such as mlx4_en and
IPoIB when the network stack attempts to join to multicast groups such
as all-hosts or the IPoIB broadcast group.

It supports establishing passive open connection through firmware filter work
request. Passive open connection will go through this path as now instead of
listening server we create a server filter which will redirect the incoming SYN
packet to the offload queue.

It divides filter region into regular filters and server filter portion. It
introduces new server filter region which will be exclusively used for creating
server filters. This region will not overlap with regular filter region.

It provides new API cxgb4_alloc_sftid in LLD for getting stid in case of LE
hash collision path. This new stid will be used to open server filter in the
filter region.

This patch adds framework for managing filters and to use T4's filter

filter at a specified index to get the work done. It hosts shadow copy of
ingress filter entry to check field size limitations and save memory in the

d23e946cb6 be2net: fix wrong frag_idx reported by RX CQ
The RX CQ can report completions with invalid frag_idx when the RXQ that
was *previously* using it, was not cleaned up properly. This hits
a BUG_ON() in be2net.

When completion coalescing is enabled on a CQ, an explicit CQ-notify
(with rearm) is needed for each compl, to flush partially coalesced CQ
entries that are pending DMA.

In be_close(), this fix now notifies CQ for each compl, waits explicitly
for the flush compl to arrive and complains if it doesn't arrive.

Also renaming be_crit_error() to be_hw_error() as it's the more
appropriate name and to convey that we don't wait for the flush compl
only when a HW error has occurred.

Change Details:

                RX_E_STARTED event does enet stop
                RX_E_STOPPED event does rx_cleanup_cbfn
        rx_cleanup_cbfn in this case is called without post_cbfn. post_cbfn
        happens only after RX_E_STARTED event is received in start_wait. Without
        doing post_cbfn, NAPI remains disabled and in cleanup we try to disable
        again causing endless wait. ifconfig process and other workers can thus
        get stuck.
 -      Introducing start_stop_wait state for Rx. This state handles the case of
        if post_cbfn is not done simply do stop without the cleanup.

The {read,write}s{b,w,l} operations are not defined by all
architectures and are being removed from the asm-generic/io.h
interface.

c63da990cd bnx2x: Prevent link flaps when booting from SAN.
It is possible that the driver is configured to operate with a certain
link configuration which differs from the link's configuration during
boot from SAN - this would cause the driver to flap the link.

Said flap may be missed by specific switches, causing dcbx convergence
to be too long and boot sequence to fail. Convergence is longer because
switch ignores new dcbx packets due to counters mismatch, as only host
side reset the counters due to the link flap.

This patch causes the driver to ignore user's initial configuration during
boot from SAN, and continues with the existing link configuration.

cb6d0f5eef ixgbe: check whether thermal sensor is enabled.
The X540's internal thermal sensor should not be enabled for all devices, but
only those devices which enable it in the NVM image. It is expected that
actively cooled devices will have it enabled, but passively cooled devices might
not want it enabled. This is due to passively cooled devices operating very near
the thermal threshold, sometimes within the margin of error of the thermal
sensor. Thus these devices may not be good candidates for using the thermal
sensor.

This patch uses the enabled bit in the FWSM register to check whether we should
be enabling the thermal sensor, and only sets the THERMAL_SENSOR_CAPABLE flag
for those devices which have it enabled.

Frequency adjustment is performed using hardware with a 24 bit
accumulator and a programmable correction value. On each clk, the
correction value gets added to the accumulator and when it overflows,
the time counter is incremented/decremented and the accumulator reset.

So conversion from ppb to correction value is
	ppb * (1 << 24) / 1000000000

1c85382e30 sky2: fix cleanup sequence in probe() function
The cleanup sequence in sky2_probe() that is called in case of an error is
mixed up in different places:

- pci_disable_device() is not called in each case the device has been enabled
before

- same for pci_disable_msi(): test_msi() may return with an error != EOPNOTSUPP
(due to failure of request_irq()). In that case msi is not disabled

- also failure of register_netdev() does not disable msi

This patch fixes the concerning parts.

cb64edb6b8 8139cp: properly support change of MTU values [v2]
The 8139cp driver has a change_mtu function that has not been
enabled since the dawn of the git repository. However, the
generic eth_change_mtu is not used in its place, so that
invalid MTU values can be set on the interface.

Original patch salvages the broken code for the single case of
setting the MTU while the interface is down, which is safe
and also includes the range check.  Now enhanced to support up
or down interface.

v2: fix case where rxbufsz isn't changed in the up state case

Original patch from
http://lkml.indiana.edu/hypermail/linux/kernel/1202.2/00770.html

Testing: has been test on virtual 8139cp setup without issue,
have no access real hardware 8139cp, need testing help.

If fan failure is detected, MCP prevents PCI I/O registers from being

This patch recognizes such an event occurred and gracefully terminates

ebf98e797b sfc: Fix timekeeping in efx_mcdi_poll()
efx_mcdi_poll() uses get_seconds() to read the current time and to
implement a polling timeout.  The use of this function was chosen
partly because it could easily be replaced in a co-sim environment
with a macro that read the simulated time.

Unfortunately the real get_seconds() returns the system time (real
time) which is subject to adjustment by e.g. ntpd.  If the system time
is adjusted forward during a polled MCDI operation, the effective
timeout can be shorter than the intended 10 seconds, resulting in a
spurious failure.  It is also possible for a backward adjustment to
delay detection of a areal failure.

Use jiffies instead, and change MCDI_RPC_TIMEOUT to be denominated in
jiffies.  Also correct rounding of the timeout: check time > finish
(or rather time_after(time, finish)) and not time >= finish.

778cdaf639 sfc: Remove confusing MMIO functions
efx_writed_table() uses a step of 16 bytes but efx_readd_table() uses
a step of 4 bytes.  Why are they different?

Firstly, register access is asymmetric:

- The EVQ_RPTR table and RX_INDIRECTION_TBL can (or must?) be written
  as dwords even though they have a step size of 16 bytes, unlike
  most other CSRs.
- In general, a read of any width is valid for registers, so long as
  it does not cross register boundaries.  There is also no latching
  behaviour in the BIU, contrary to rumour.

We write to the EVQ_RPTR table with efx_writed_table() but never read
it back as it's write-only.  We write to the RX_INDIRECTION_TBL with
efx_writed_table(), but only read it back for the register dump, where
we use efx_reado_table() as for any other table with step size of 16.

We read MC_TREG_SMEM with efx_readd_table() for the register dump, but
normally read and write it with efx_readd() and efx_writed() using
offsets calculated in bytes.

Since these functions are trivial and have few callers, it's clearer
to open-code them at the call sites.  While we're at it, update the
comments on the BIU behaviour again.

Merge tag 'mvebu_everything_for_3.8' of git://git.infradead.org/users/jcooper/linux into late/mvebu

From Jason Cooper. Unfortunately this is a combined branch with all
mvebu code as one drop, something we normally try to avoid and instead
slice vendor topics across our branches. Hopefully we can avoid doing
this again for 3.9!

mvebu everything for v3.8
 - due to the complex interdependencies of the received pull requests
   I decided to keep this in one branch the way they recommended merging it
 - this was their first attempt at doing pull requests, we'll work on it
   with them

 - added SMP support for mvebu SoCs
 - added coherency fabric
 - added mdio and mvneta drivers
 - added mirabox board
 - added openblocks ax3-4 board
 - clock fixes and improvements
 - converted mv_xor driver to devicetree (extensive series in itself)

e49cc34f7a be2net: fix INTx ISR for interrupt behaviour on BE2
On BE2 chip, an interrupt may be raised even when EQ is in un-armed state.
As a result be_intx()::events_get() and be_poll:events_get() can race and
notify an EQ wrongly.

Fix this by counting events only in be_poll(). Commit 0b545a629 fixes
the same issue in the MSI-x path.

But, on Lancer, INTx can be de-asserted only by notifying num evts. This
is not an issue as the above BE2 behavior doesn't exist/has never been
seen on Lancer.

Taking PHY lock was initially required only on specific boards which had their

when NCSI is present, the PHY lock will always be taken.

5a1fbf4046 bnx2x: Fix SFP+ current leakage
Per measurements, the SFP+ suffered from small current leakage in two cases:
 - When no module was plugged and TX laser was disabled. The fix was to enable
   it, and when module is plugged in, check if it needs to be disabled.
 - When over-current event occurs due to invalid SFP+ module, the HW basically
   shuts down the current for this module, but the SW needs to complete this
   by issuing a power down via a GPIO.

55386fe883 bnx2x: Change MDIO clock settings
When drivers works on top of an old bootcode, it is theoretically subjected to
MDC/MDIO failures since the MDIO clock is set in the beginning of each sequence,
rather than per CL45 command. On rare cases an old bootcodes may change that in
the middle, so to address that, the MDIO clock is set for each CL45 access.
In addition, setting the MDIO clock is now done per EMAC base, and
not per port number, since a specific port can potentially use both EMACs for
different PHY accesses.

Parikh, Neerav
2afaa00d2f ixgbe: Fix incorrect disabling of Tx hang check in case of PFC
The XOFF received statistic registers are per priority based and not per
traffic class. The ixgbe driver was incorrectly considering them to be for
each traffic class; and then disabling the "Tx hang" check for the queues
that belonged to the particular traffic class that had received PFC frames.

The above logic worked fine in scenario where the user priority and traffic
class number matched e.g. priority 0 is mapped to traffic class 0 and so on.
But, when multiple user priorities are mapped to a single traffic class or
when user priorities and traffic class numbers do not line up; the ixgbe
driver may disable the "Tx hang" check for queues belonging to a traffic
class that did not receive PFC frames and keep the "Tx hang" check enabled
for the queues that did receive the PFC frames.

This patch corrects the above in the code by considering the statistics
on a per priority basis; then getting the traffic class the user priority
belongs to and disabling the "Tx hang" check for queues that belong
to that traffic class.

62a2ab935c stmmac: add Rx watchdog support to mitigate the DMA irqs
GMAC devices newer than databook 3.40 has an embedded timer
that can be used for mitigating the number of interrupts.
So this patch adds this optimizations.

At any rate, the Rx watchdog can be disable (on bugged HW) by
passing from the platform the riwt_off field.

In this implementation the rx timer stored in the Reg9 is fixed
to the max value. This will be tuned by using ethtool.

V2: added a platform parameter to force to disable the rx-watchdog
for example on new core where it is bugged.

V3: do not disable NAPI when Rx watchdog is used.

V4: a new extra statistic field has been added to show the early
receive status in the interrupt handler.
This patch also adds an extra check to avoid to call
napi_schedule when the DMA_INTR_ENA_RIE bit is disabled in the
Interrupt Mask register.

9125cdd1be stmmac: add the initial tx coalesce schema
This patch adds a new schema used for mitigating the
number of transmit interrupts.
It is based on a SW timer and a threshold value.
The timer is used to periodically call the stmmac_tx_clean
function; the threshold is used for setting the IC (Interrupt
on Completion bit). The ISR will then invoke the poll method.
Also the patch improves some ethtool stat fields.

V2: review the logic to manage the IC bit in the TDESC
that was bugged because it didn't take care about the
fragments. Also fix the tx_count_frames that has not to be
limited to TX DMA ring. Thanks to Ben Hutchings.

08ff32352d mlx4: 64-byte CQE/EQE support
ConnectX-3 devices can use either 64- or 32-byte completion queue
entries (CQEs) and event queue entries (EQEs).  Using 64-byte
EQEs/CQEs performs better because each entry is aligned to a complete
cacheline.  This patch queries the HCA's capabilities, and if it
supports 64-byte CQEs and EQES the driver will configure the HW to
work in 64-byte mode.

The 32-byte vs 64-byte mode is global per HCA and not per CQ or EQ.

Since this mode is global, userspace (libmlx4) must be updated to work
with the configured CQE size, and guests using SR-IOV virtual
functions need to know both EQE and CQE size.

In case one of the 64-byte CQE/EQE capabilities is activated, the
patch makes sure that older guest drivers that use the QUERY_DEV_FUNC
command (e.g as done in mlx4_core of Linux 3.3..3.6) will notice that
they need an update to be able to work with the PPF. This is done by
changing the returned pf_context_behaviour not to be zero any more. In
case none of these capabilities is activated that value remains zero
and older guest drivers can run OK.

The SRIOV related flow is as follows

1. the PPF does the detection of the new capabilities using
   QUERY_DEV_CAP command.

2. the PPF activates the new capabilities using INIT_HCA.

3. the VF detects if the PPF activated the capabilities using
   QUERY_HCA, and if this is the case activates them for itself too.

Note that the VF detects that it must be aware to the new PF behaviour
using QUERY_FUNC_CAP.  Steps 1 and 2 apply also for native mode.

User space notification is done through a new field introduced in
struct mlx4_ib_ucontext which holds device capabilities for which user
space must take action. This changes the binary interface so the ABI
towards libmlx4 exposed through uverbs is bumped from 3 to 4 but only
when **needed** i.e. only when the driver does use 64-byte CQEs or
future device capabilities which must be in sync by user space. This
practice allows to work with unmodified libmlx4 on older devices (e.g
A0, B0) which don't support 64-byte CQEs.

In order to keep existing systems functional when they update to a
newer kernel that contains these changes in VF and userspace ABI, a
module parameter enable_64b_cqe_eqe must be set to enable 64-byte
mode; the default is currently false.

a9dbe40fc1 8139cp: set ring address after enabling C+ mode
This fixes (for me) a regression introduced by commit b01af457 ("8139cp:
set ring address before enabling receiver"). That commit configured the
descriptor ring addresses earlier in the initialisation sequence, in
order to avoid the possibility of triggering stray DMA before the
correct address had been set up.

Unfortunately, it seems that the hardware will scribble garbage into the
TxRingAddr registers when we enable "plus mode" Tx in the CpCmd
register. Observed on a Traverse Geos router board.

To deal with this, while not reintroducing the problem which led to the
original commit, we augment cp_start_hw() to write to the CpCmd register
*first*, then set the descriptor ring addresses, and then finally to
enable Rx and Tx in the original 8139 Cmd register. The datasheet
actually indicates that we should enable Tx/Rx in the Cmd register
*before* configuring the descriptor addresses, but that would appear to
re-introduce the problem that the offending commit b01af457 was trying
to solve. And this variant appears to work fine on real hardware.

0b545a6291 be2net: fix a possible events_get() race on BE2
On BE2 chip, an interrupt being raised even when EQ is in un-armed state has
been observed a few times.  This is not expected and has never been
observed on BE3/Lancer chips.

As a consequence, be_msix()::events_get() and be_poll()::events_get()
can race and notify an EQ wrongly causing a CEV UE. The other possible
side-effect would be traffic stalling because after notifying EQ,
napi_schedule() is ignored as NAPI is already running.

This patch fixes this issue by counting events only in be_poll().
