Subject: [net-next v1 3/5] ice: Add AdminQ commands for FW update
From: "Cudzilo, Szymon T" <szymon.t.cudzilo@...el.com>
Add structures, identifiers, and helper functions for several AdminQ
commands related to performing a firmware update for the ice hardware.
These will be used in future code for implementing the devlink
.flash_update handler.
