Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2023-09-18 (ice)

This series contains updates to ice driver only.

Sergey prepends ICE_ to PTP timer commands to clearly convey namespace
of commands.

Karol adds retrying to acquire hardware semaphore for cross-timestamping
and avoids writing to timestamp registers on E822 devices. He also
renames some defines to be more clear and align with the data sheet.
Additionally, a range check is moved in order to reduce duplicated code.

Jake adds cross-timestamping support for E823 devices as well as adds
checks against netlist to aid in determining support for GNSS. He also
corrects improper pin assignment for certain E810-T devices and
refactors/cleanups PTP related code such as adding PHY model to ease checks
for different needed implementations, removing unneeded EXTTS flag, and
adding macro to check for source timer owner.
