The interface would not function after the system had been woken up
after have been suspended (echo mem > /sys/power/state) cycle. The
reason for this is that all device registers have been reset to its
default values. This patch adds sleep suspend and resume functions that
detached the interface at suspend and restore the registers and reattach
the interface at resume.
Only the registers that are only configured at probe time needs to be
explicitly restored by the resume handler. All other registers are
reconfigured by either reopening the device in the resume handler (if
the device was running when the system was suspended) or when the
interface is opened by a user at a later time.

The struct cpdma_desc_pool->used_desc field can be safely removed from
CPDMA driver (and hot patch) because used_descs counter is used just
for pool consistency check at CPDMA deinitialization and now this
check can be re-implemnted using gen_pool_size(pool->gen_pool) !=
gen_pool_avail(pool->gen_pool).
More over, this will allow to get rid of warnings in
cpdma_desc_pool_destro()-> WARN_ON(pool->used_desc) which may happen
because the used_descs is used unprotected, since CPDMA has been
switched to use genalloc, and may get wrong values on SMP.
Hence, remove used_desc from struct cpdma_desc_pool.

The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with
BHs disabled. The driver currently issues the required cmds to the FW in
these contexts and polls on completions from the FW, while BHs remain
disabled. This can cause either packet loss or packet reception to be
delayed on that CPU.
This patch defers processing of the above cmds to a separate workqueue.
With this change, FW cmds are now issued only in process context.
Now that the FW cmds are issued only in process context, they can sleep
waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock)
calls are now replaced with mutex calls.
Also a new rx_filter_lock is now needed to protect the RX filtering fields
like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

Eachtime the ndo_set_rx_mode() routine is called, the driver programs the
multicast list in the adapter without checking if there are any changes to
the list. This leads to a flood of RX_FILTER cmds when a number of vlan
interfaces are configured over the device, as the ndo_ gets
called for each vlan interface. To avoid this, we now use __dev_mc_sync()
and __dev_uc_sync() API, but only to detect if there is a change in the
mc/uc lists. Now that we use this API, the code has to be-designed to
issue these API calls for each invocation of the be_set_rx_mode() call.

The Lancer FW has a bug due to which in some cases vlan-promisc setting
is cleared eventhough the vlan-list programming did not succeed (via
VLAN_CONFIG) cmd. The driver has no way of knowing if the vlan-promisc
mode was cleared or not when this cmd fails. To work around this issue,
this patch first explicitly clears the vlan-promisc mode via RX_FILTER
cmd and then tries to program the vlan list.

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

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
get hardware wol setting, driver will write or read hardware registers.
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,

Use of_platform_depopulate() in cpsw_remove() instead of
of_device_unregister(), because CSPW child devices will not be
recreated otherwise on next insmod. of_platform_depopulate() is
correct way now as it will ensure that all steps done in
of_platform_populate() are reverted, including cleaning up of
OF_POPULATED flag.

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
anymore.

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.

qede is requesting firmware to remove the vlan filter.
This currently happens even if the vlan wasn't previously

For PFs this doesn't cause any issues as the firmware
would simply ignore the removal request. But for VFs their
parent PF is holding an accounting of the configured vlans,

removal request.

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.

10GbE Intel Wired LAN Driver Updates 2016-07-22
This series contains updates to ixgbe and ixgbevf only.
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
ixgbevf_write_msg_read_ack(), other functions are performing the same
operations done here.
Colin Ian King removes a redundant check on ret_val, since ret_val has
not changed since the previous check.
