Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2024-02-06 (ixgbe)

This series contains updates to ixgbe driver only.

Jedrzej continues cleanup work from conversion away from ixgbe_status;
s32 values are changed to int, various style issues are addressed, and
some return statements refactored to address some smatch warnings.

* '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ixgbe: Clarify the values of the returning status
  ixgbe: Rearrange args to fix reverse Christmas tree
  ixgbe: Convert ret val type from s32 to int
====================
