From cdfa9f6444ced9425e8e4fe4c2975a620e664b77 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 31 Mar 2009 20:38:56 +0000 Subject: igb: cleanup igb loopback path The code path for setting up phy loopback testing was out of date and was setting bits it didn't need to. This change cleans up the code path and removes some code that has no effect on teh driver. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
