This patch fixes a data structure corruption bug in the SRIOV VF mailbox

driver is accessing and updating qlcnic_async_work_list_struct entry fields
in the async work list. These fields could be concurrently accessed by the
work function resulting in data corruption.
This patch restructures async mbx command handling by using a separate
async command list instead of using a list of work_struct structures.
A single work_struct is used to schedule and handle the async commands
with proper locking mechanism.

Building with -Wmaybe-uninitialized shows a potential use of

drivers/net/ethernet/apm/xgene/xgene_enet_hw.c:802:23: warning: 'phy_dev' may be used uninitialized in this function [-Wmaybe-uninitialized]
Although the compiler correctly identified this based on the function,
the current code is still safe as long dev->of_node is non-NULL
for the case of CONFIG_ACPI=n, which is currently the case.
The warning is now disabled by default, but still appears when
building with W=1, and other build test tools should be able to
detect it as well. Adding an #else clause here makes the code
more robust and makes it clear to the compiler that this cannot
happen.

When there is no AC power, NIC may not work after changing mac address.
Please refer to following link.
http://www.spinics.net/lists/netdev/msg356572.html
This issue is caused by runtime power management. When there is no AC
power, if we put NIC down (ifconfig down), the driver will be in runtime
suspend state and hardware will be put into D3 state. During this time,
driver cannot access hardware regisers. So if you set new mac address
during this time, it will not be set to hardware. After resume, NIC will
keep using the old mac address and the network will not work normally.
In this patch I add detecting runtime pm status when setting mac address.
If driver is in runtime suspend state, it will skip setting mac address, keep
the new mac address, and set the new mac address during runtime resume.

NIC will be put into D3 state during runtime suspend state. When set or

If we set or get hardware wol setting in runtime suspend state, because
NIC will in D3 state, the hardware registers read by driver will return all
0xff. That will let driver thinking register flag is not toggled and
then prints the warning message "rtl_counters_cond == 1 (loop: 1000,

For fixing this issue, add checking driver's pm runtime status in

The L3 error will be generated and system will crash during unloading
of CPSW driver if CPSW is used as module and ethX devices are down.
This happens because CPSW can be power off by PM runtime now when ethX
devices are down.
Hence, ensure that CPSW powered up by PM runtime before performing any
deinitialization actions which require CPSW registers access. In case
of PM runtime error just leave cpsw_remove() as we can't do anything

The commit 637d3e9973 ("cxgb4: Discard the packet if the length is
greater than mtu") introduced a regression in the VLAN interface
performance when Tx VLAN offload is disabled.
Check if skb is tagged, regardless of whether it is hardware accelerated
or not. Presently we were checking only for hardware acclereated one,
which caused performance to drop to ~0.17Mbps on a 10GbE adapter for
VLAN interface, when tx vlan offload is turned off using ethtool.
The ethernet head length calculation was going wrong in this case, and
driver ended up dropping packets.

Each PF/VF has a limited number of vlan filters for
configuration purposes; This information is passed to qede
and is used to prevent over-usage - once a vlan is to be
configured and no filter credit is available, the driver
would switch into working in vlan-promisc mode.
Problem is the credit pool is shared by both PFs and VFs,
and currently PFs aren't deducting the filters that are
reserved for their VFs from their quota, which may lead
to some vlan filters failing unknowingly due to lack of credit.

would simply ignore the removal request. But for VFs their
parent PF is holding an accounting of the configured vlans,
and such a request would cause the PF to fail the VF's
removal request.
Simply fix this for both PFs & VFs and don't remove filters
that were not previously added.

The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.
No functional changes were introduced.

The workqueue health->wq was used as per device private health thread.
This was done to perform delayed work.
The workqueue has a single workitem(&health->work) and
hence doesn't require ordering. It is involved in handling the health of
the device and is not being used on a memory reclaim path.
Hence, the singlethreaded workqueue has been replaced with the use of
system_wq.
Work item has been flushed in mlx5_health_cleanup() to ensure that
there are no pending tasks while disconnecting the driver.

Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where
the index is not equal to zero. Fixes an issue where mac->ops.setup_fc
can be NULL for backplanes which can cause the driver to crash on load.
Don fixes the second parameter of the LED functions, which is the index to
the LED we are interested in affecting. Fixed variable to store register
reads to unsigned integer. Adds support for the new x553 hardware into
ixgbevf. Fixed a missing rtnl lock around ixgbevf_reinit_locked().
Fixed an issue where in ixgbevf_reset_subtask() was not verifying that
the port has been removed. Cleans up the initial crosstalk fix, since
the SFP that indicates the presence of a SFP+ module changes between
hardware types.
Babu Moger fixes typo in freeing IRQ, since the array subscript increments
after the execution of the statement.
Wei Yongjun adds the missing destroy_workqueue() before returning from
ixgbe_init_module() in the error handling case.
Tony adds range checking for setting the MTU from the VF, where the PF can
return a NACK but this was not passed on to the VF, so propagate the
results from the PF to the VF so errors can be reported. Consolidates
mailbox read and write functions, since the recent changes to

operations done here.

40GbE Intel Wired LAN Driver Updates 2016-07-22
This series contains updates to i40e and i40evf.
Heinrich Schuchardt found a possible null pointer being dereferenced in
i40e_debug_aq(), fixed the issue by doing the variable assignment after
we are sure the pointer is not null.
Avinash fixed an issue when link was down, we were not showing the
correct advertised link modes.
Mitch cleans up a useless initializer since the variable is assigned
right away. Refactors the receive filter handling to properly track
filter adds and deletes so the driver will not lose filters during a
reset and up/down cycles. Also added a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Catherine removes a device id which is not needed (or used). Moves
a mutex lock since we need to lock the client list around the
i40e_client_release() call to prevent the release from interrupting
the client instances while they are being added.
Joshua adds Hyper-V specific VF device ids.
Amitoj Kaur Chawla cleans up a redundant memset() call before a memcpy().
Stefan Assmann adds the missing link advertise for some x710 NICs.
Tushar Dave fixes and issue found on SPARC, where a PF reset clears MAC
filters and if a platform-specific MAC address is used, the driver has
to explicitly write default MAC address to MAC filters otherwise all
incoming traffic destined to the default MAC address will be dropped
after reset.

This patch offloads port mirroring directives to hw using the matchall TC
with action mirror. It includes both the implementation of the
ndo_setup_tc function for the spectrum driver and the spectrum hardware
offload configuration code.
The hardware offload code is basically two new functions which are capable
of adding and removing a new mirror ports pair. It is done using the MPAT,
MPAR and SBIB registers:
- A new Switch-Port Analyzer (SPAN) entry is added using MPAT to the 'to'
port.
- The 'to' port is bound to the SPAN entry using MPAR register.
- In case of egress SPAN, the 'to' port gets a new internal shared
buffer using SBIB register.
In addition, a new database was added to the mlxsw_sp struct to store all
the SPAN entries and their bound ports list. The number of supported SPAN
entries is determined by resource query.

Properly track filter adds and deletes so the driver doesn't lose filters
during resets and up/down cycles. Add a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Implement a simple state machine so the driver can track the status of
each filter throughout its lifecycle. Properly manage the overflow promiscuous
state for the each VSI, and provide a way for the driver to detect when to exit
overflow promiscuous mode.
Remove all possible default MAC filters that the firmware may have set up so
that the driver can manage these correctly, particularly when VLANs come into
play. Remove the LAA flag for filters; instead just send whatever we get through
set_mac to the firmware as the LAA for wakeup purposes.
Finally, add the state of each filter to debugfs output so we can see what's
going on inside the driver's pointy little head.

100GbE Intel Wired LAN Driver Updates 2016-07-20
This series contains updates to fm10k only.
Ngai-Mint provides a fix to clear PCIE_GMBX bits to ensure the proper
functioning of the mailbox global interrupt after a data path reset.
Jake provides most of the patches in the series, starting with a early
return from fm10k_down() if we are already down to prevent conflict with
other threads. Fixed an issue where fm10k_update_stats() could cause
a null pointer dereference, specifically if it is called when we are going
down and the rings have been removed. Cleans up and fixes the data path
reset flow, Tx hang routine and stop_hw(). Re-worked the fm10k_reinit()
to be more maintainable and fixed several inconsistencies with the work
flow. Implemented fm10k_prepare_suspend() and fm10k_handle_resume()
which abstract around the now existing fm10k_prepare_for_reset and
fm10k_handle_reset. The new functions also handle stopping the service
task, which is something that the original re-init flow does not need.
Fixed an issue where if an FLR occurs, VF devices will be knocked out of
bus master mode, and the driver will be unable to recover from the reset
properly, so ensure bus master is enabled after every reset. Fixed an
issue where a reset will occur as if for no reason, regularly every few
minutes until the switch manager software is loaded, which is caused
by continuously requesting the lport map so only do the request after
we have verified the switch mailbox is tx_ready.

If the fm10k interface is brought up, but the switch manager software is
not running, the driver will continuously request the lport map every
few seconds in the base driver watchdog routine. Eventually after
several minutes the switch mailbox Tx fifo will fill up and the mailbox
will timeout, resulting in a reset. This reset will appear as if for no
reason, and occurs regularly every few minutes until the switch manager
software is loaded.
Prevent this from happening by only requesting the lport map after we've
verified the switch mailbox is tx_ready. In order to simplify code logic
and reduce code duplication, implement this as a new function pointer
"mac.ops.request_lport_map" which the VF will not implement. Otherwise,
we have to duplicate the tx_ready check outside of
fm10k_get_host_state_generic, or re-implement most of
fm10k_get_host_state_generic in the pf version.
The resulting code is simpler and easier to understand, and prevents the
PF from continuously requesting lport map and filling the Tx fifo of
a switch mailbox that isn't ready.

If an FLR occurs, VF devices will be knocked out of bus master mode, and
the driver will be unable to recover from the reset properly, resulting
in malicious driver events and an infinite reset loop. In the normal
case, the bus master mode will already be enabled and this call will
essentially be a no-op. Since we're doing this every reset, it is
possible we could remove the other calls to pci_set_master() but it

When a function level PCI reset is triggered using sysfs, it calls the
driver's .reset_notify error handler. Implement a handler based on the
now split fm10k_prepare_for_reset and fm10k_handle_reset functions, so
that we fully reset the driver when the PCI function level reset occurs.
This also ensures the reset is handled in a clean way by first disabling
all the driver bits first and then restoring them after the function
reset. Previously the stack simply performed a blind function reset and
our driver didn't take any part in the process.

There are several flows in the driver which perform the similar function
of tearing down software and restoring software to recover from certain
errors or PCIe events, including:
* fm10k_reinit
* fm10k_suspend/resume
* fm10k_io_error_detected/fm10k_io_resume
In addition, we want to implement a .reset_notify() handler as well
which will also perform similar function.
Rework how the driver codes reset and resume flows by separating out the
reinit logic into two functions "fm10k_prepare_for_reset" and
"fm10k_handle_reset". This first step will allow us to re-use this
functionality in the similar blocks of code instead of re-coding the
same sequence of events slightly different.
The end result should be more maintainable and correct, fixing several
inconsistencies with the work flow.
The new functions expect to take the rtnl_lock() themselves, and it does
have the unfortunate side effect of having the reinit flow take then
release then take the rtnl_lock. However, this minor downside is
out weighted by the benefits of code reduction and reducing needless
difference between these flows.

It turns out that sometimes during a reset the Tx queues will be
temporarily stuck longer than .stop_hw() expects. Work around this issue
by attempting to .stop_hw() first. If it tails, wait a number of
attempts until the Tx queues appear to be drained. After this, attempt
stop_hw() again. This ensures that we avoid waiting if we don't need to,
such as during the first initialization of a VF, and give the proper
amount of time necessary to recover from most situations. It is possible
that the hardware is actually stuck. For PFs, this is usually fixed by
a datapath reset. Unfortunately the VF cannot request a similar reset
for itself.

A while ago, an additional check for the switch being ready was added to
reset_hw. A recent refactor accidentally made this check return an error
code on failure which caused fm10k_probe to fail when the switch wasn't
brought up first. The original reasoning for the check was to prevent
additional data path reset when the fabric wasn't ready yet. However,
there isn't a compelling reason to keep the check, as the data path
reset will restore hardware to a known good state. Remove the check and
perform the data path reset regardless of the switch manager state.
An alternative fix is to return FM10K_SUCCESS instead, and bypass the
actual data path reset. This should be fine as we will perform
a reset_hw once the switch is active. However, since data path reset
will reset many parts of the hardware it seems better to just perform
the reset regardless of switch state.

Don't report FM10K_ERR_REQUESTS_PENDING when we fail to disable queues
within the timeout. This can occur due to a hardware Tx hang, or when
the switch ethernet fabric is resetting while we are transmitting
traffic. It can sometimes take up to 500ms before the Tx DMA engine
gives up. Instead, just skip the DMA engine check and perform
a data-path reset anyways. Add a statistic counter to keep track of the
number of resets occurring while we have pending DMA on the rings.
In order to prevent having to re-assign err to 0, re-order the
last few items of the reset_hw_pf function so that we don't perform
"return err" at the end.

When a data path reset is initiated, write control to the PCIE_GMBX is
yanked from the switch manager. The switch manager writes to this
register to clear mailbox global interrupt bits as part of its mailbox
interrupt handling routine. When the device recovers from the data path
reset and these bits are not cleared, it will prevent future mailbox
global interrupts from being triggered. Upon confirming that the device
has exited from a data path reset, clear these bits to ensure the proper
functioning of the mailbox global interrupt.

Also prevent updating stats while the interface is down. If we're
already updating stats, just return doing nothing. When we take the
device down, block stat updates until we come back up. This ensures that
we avoid tearing down rings when we're updating statistics, and prevents
updating statistics until we're up.
We can't re-use the __FM10K_DOWN for this because it wouldn't prevent
multiple threads from accessing statistics. Neither does it prevent the
case where we start updating stats and then start going down in another
