This series contains updates to fm10k only.
Jake provides all the changes in this series starting with fixes an issue
where VF devices may fail during an unbind/bind and we will never zero
the reference counter for the pci_dev structure. Updated the hot path
to use SW counters instead of checking for hardware Tx pending for
possible transmit hangs, which will improve performance. Fixed the NAPI
budget accounting so that fm10k_poll will return actual work done,
capped at (budget - 1) instead of returning 0. Added a check to ensure
that the device is in the normal IO state before continuing to probe,
which allows us to give a more descriptive message of what is wrong
in the case of uncorrectable AER error. In preparation for adding Geneve
Rx offload support, refactored the current VXLAN offload flow to be a bit
more generic. Added support for receive offloads on one Geneve tunnel.
Ensure that other bits in the RXQCTL register do not get cleared, to
make sure that bits related to queue ownership are maintained. Fixed
an issue in queue ownership assignment which casued a race condition
between the PF and the VF such that potentially a VF could cause FUM
fault errors due to normal PF/VF driver behavior.
The following are changes since commit 0b498a52778368ff501557d68c7b50878ab1701e:
net_sched: fix use of uninitialized ethertype variable in cls_flower
