====================
Intel Wired LAN Driver Updates 2024-03-04 (ice)

This series contains updates to ice driver only.

Jake changes the driver to use relative VSI index for VF VSIs as the VF
driver has no direct use of the VSI number on ice hardware. He also
reworks some Tx/Rx functions to clarify their uses, cleans up some style
issues, and utilizes kernel helper functions.

Maciej removes a redundant call to disable Tx queues on ifdown and
removes some unnecessary devm usages.
