====================
100GbE Intel Wired LAN Driver Updates 2021-04-08

This series contains updates to ice driver only.

Chinh adds retrying of sending some AQ commands when receiving EBUSY
error.

Victor modifies how nodes are added to reduce stack usage.

Ani renames some variables to either follow spec naming or to be inline
with naming in the rest of the driver. Ignores EMODE error as there are
cases where this error is expected. Performs some cleanup such as
removing unnecessary checks, doing variable assignments over copies, and
removing unneeded variables. Revises some error codes returned in link
settings to be more appropriate. He also implements support for new
firmware option to get default link configuration which accounts for
any needed NVM based overrides for PHY configuration. He also removes
the rx_gro_dropped stat as the value no longer changes.

Jeb removes setting specific link modes on firmwares that no longer
require it.

Brett removes unnecessary checks when adding and removing VLANs.

Tony fixes a checkpatch warning for unnecessary blank line.
