From: Alexander Duyck Date: Tue, 25 Nov 2008 09:04:03 +0000 (-0800) Subject: igb: loopback bits not correctly cleared from RCTL register X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=69d728baf620839d1a3c874eecac316729f89de4;p=linux-beck.git igb: loopback bits not correctly cleared from RCTL register This change forces the bits to 0 by using an &= operation with an inverted mask of all options instead of using an |= with a value of 0.
