Tony Nguyen says:
====================
Intel Wired LAN Driver Updates 2022-02-10
Dan Carpenter propagates an error in FEC configuration.
Jesse fixes TSO offloads of IPIP and SIT frames.
Dave adds a dedicated LAG unregister function to resolve a KASAN error
and moves auxiliary device re-creation after LAG removal to the service
task to avoid issues with RTNL lock.
