From e017b60316468f21a63bdd4affefaf81a7f988fd Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 25 Mar 2010 17:15:06 +0000 Subject: [PATCH] igb: use correct bits to identify if managability is enabled igb was previously checking the wrong bits in the MANC register to determine if managability was enabled. As a result it was incorrectly powering down and resetting the phy when it didn't need to. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
