This series contains updates to igc and i40e drivers.
Kai-Heng Feng fixes igc to report unknown speed and duplex during suspend
as an attempted read will cause errors.
Kevin Lo sets the default value to -IGC_ERR_NVM instead of success for
writing shadow RAM as this could miss a timeout. Also propagates the return
value for Flow Control configuration to properly pass on errors for igc.
Aleksandr reverts commit 2ad1274fa35a ("i40e: don't report link up for a VF
who hasn't enabled queues") as this can cause link flapping.
v2: Additional information to commit message of i40e revert patch.
The following are changes since commit eb4e8fac00d1e01ada5e57c05d24739156086677:
neighbour: Prevent a dead entry from updating gc_list
and are available in the git repository at:

Similar to commit 165ae7a8feb5 ("igb: Report speed and duplex as unknown
when device is runtime suspended"), if we try to read speed and duplex
sysfs while the device is runtime suspended, igc will complain and
stops working:

The more generic approach will be wrap get_link_ksettings() with begin()
and complete() callbacks, and calls runtime resume and runtime suspend
routine respectively. However, igc is like igb, runtime resume routine
uses rtnl_lock() which upper ethtool layer also uses.
So to prevent a deadlock on rtnl, take a different approach, use
pm_runtime_suspended() to avoid reading register while device is runtime
suspended.

This patch sets the default return value to -IGC_ERR_NVM in
igc_write_nvm_srwr. Without this change it wouldn't lead to a shadow RAM

This reverts commit 2ad1274fa35ace5c6360762ba48d33b63da2396c
VF queues were not brought up when PF was brought up after being
downed if the VF driver disabled VFs queues during PF down.
This could happen in some older or external VF driver implementations.
The problem was that PF driver used vf->queues_enabled as a condition
to decide what link-state it would send out which caused the issue.
Remove the check for vf->queues_enabled in the VF link notify.
Now VF will always be notified of the current link status.
Also remove the queues_enabled member from i40e_vf structure as it is
not used anymore. Otherwise VNF implementation was broken and caused
a link flap.
The original commit was a workaround to avoid breaking existing VFs though
it's really a fault of the VF code not the PF. The commit should be safe to
revert as all of the VFs we know of have been fixed. Also, since we now
know there is a related bug in the workaround, removing it is preferred.
