[Intel-wired-lan] [PATCH] i40e: Set PHY Access flag on X722

[Intel-wired-lan] [PATCH] i40e: Set PHY Access flag on X722

[Alice Michael]

From: Adam Ludkiewicz <adam.ludkiewicz@intel.com>

The X722 FW API version 1.9 adds support for accessing PHY
registers with Admin Queue Command. This enables reading
EEPROM data from (Q)SFP+ transceivers, what was previously
possible only on X710 devices.
