====================
Intel Wired LAN Driver Updates 2023-05-16

This series contains updates to ice and iavf drivers.

Ahmed adds setting of missed condition for statistics which caused
incorrect reporting of values for ice. For iavf, he removes a call to set
VLAN offloads during re-initialization which can cause incorrect values
to be set.

Dawid adds checks to ensure VF is ready to be reset before executing
commands that will require it to be reset on ice.
