From 76886596921dd0e058f7f0a16de6151629390d15 Mon Sep 17 00:00:00 2001 From: "Akeem G. Abodunrin" Date: Tue, 17 Jul 2012 04:51:18 +0000 Subject: [PATCH] igb: reset PHY in the link_up process to recover PHY setting after power down. There was a previous patch to resolve issue with 82576 losing PHY setting after PHY power down. However that previous implementation triggered speed mismatch and occasional link lost. Now, this patch resolves both initial PHY setting and speed mismatch issues. Signed-off-by: Akeem G.
