From 739c48e581242c57425de1a632d307e4c7a036dd Mon Sep 17 00:00:00 2001

Subject: [PATCH 08/10] amd-xgbe: rrc is required only for Fixed PHY
configuration
xgbe driver does RRC in every 10 seconds if the link is down.
When AN is enabled and KR training is in progress,
doing RRC cause KR training failure. The patch enables RRC only
if AN is disabled.
