Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 



Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2022-11-23 (ice)

This series contains updates to ice driver only.

Karol adjusts check of PTP hardware to wait longer but check more often.

Brett removes use of driver defined link speed; instead using the values
from ethtool.h, utilizing static tables for indexing.

Ben adds tracking of stats in order to accumulate reported statistics that
were previously reset by hardware.

Marcin fixes issues setting RXDID when queues are asymmetric.

Anatolii re-introduces use of define over magic number; ICE_RLAN_BASE_S.
---
v3:
 - Dropped, previous, patch 2
v2:
Patch 5
 - Convert some allocations to non-managed
 - Remove combined error checking; add error checks for each call
 - Remove excess NULL checks
 - Remove unnecessary NULL sets and newlines
====================
