====================
Intel Wired LAN Driver Updates 2023-01-19 (ice)

This series contains updates to ice driver only.

Tsotne and Anatolii implement new handling, and AdminQ command, for
firmware LLDP, adding a pending notification to allow for proper
cleanup between TC changes.

Amritha extends support for drop action outside of switchdev.

Siddaraju adjusts restriction for PTP HW clock adjustments.

Ani removes an unneeded non-null check and improves reporting of some link
modes to utilize more appropriate values.

Jesse adds checks to ensure PF VSI type.

Przemek combines duplicate checks of the same condition into one check.

Tony makes various cleanups to code: removes comments for cppcheck
suppressions, reduces scope of some variables, changes some return
statements to reflect an explicit 0 return, matches naming for function
declaration and definition, adds local variable for readability, and
fixes indenting.

Sergey separates DDP (Dynamic Device Personalization) code into its own
file.
