====================
40GbE Intel Wired LAN Driver Updates 2022-03-17

This series contains updates to i40e and igb drivers.

Tom Rix moves a conversion to little endian to occur only when the
value is used for i40e. He also zeros out a structure to resolve
possible use of garbage value for igb as reported by clang.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  igb: zero hwtstamp by default
  i40e: little endian only valid checksums
