6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Karol Kolacinski <karol.kolacinski@xxxxxxxxx>
[ Upstream commit d79c304c76e9b30ff5527afc176b5c4f9f0374b6 ]
Current implementation checks revision of all PHYs on all PFs, which is
incorrect and may result in initialization failure. Check only the
revision of the current PHY.
Fixes: 7cab44f1c35f ("ice: Introduce ETH56G PHY model for E825C products")
