Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2023-11-13 (i40e)

This series contains updates to i40e driver only.

Justin Bronder increases number of allowable descriptors for XL710
devices.

Su Hui adds error check, and unroll, for RSS configuration.

Andrii changes module read error message to debug and makes it more
verbose.

Ivan Vecera performs numerous clean-ups and refactors to driver such as
removing unused defines and fields, converting use of flags to bitmaps,
adding helpers, re-organizing code, etc.
