From 5755143dd18d3b7fa97b419d18d9bb4764b7b46f Mon Sep 17 00:00:00 2001 From: Dave Ertman Date: Wed, 19 Sep 2018 17:23:15 -0700 Subject: [PATCH] ice: Check for actual link state of port after reset We are currently replaying the link state of a port after a reset, but it is possible that the link state of a port can change during the reset process. So check for the current link state of a port during the rebuild process of a reset.
