Subject: [Intel-wired-lan] [PATCH iwl-next 2/2] ice: extend dump serdes equalizer values feature

Extend the work done in commit 70838938e89c ("ice: Implement driver
functionality to dump serdes equalizer values") by adding the new set of
Rx registers that can be read using command:
  $ ethtool -d interface_name

Rx equalization parameters are E810 PHY registers used by end user to
gather information about configuration and status to debug link and
connection issues in the field.
