From a20e4cf9e6a37e40532593e00df153d01e317baf Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Fri, 21 Nov 2008 17:01:35 -0800 Subject: e1000e: fix incorrect link status when switch module pulled On 82571 with SerDes, the true link state is not always correct when read from the STATUS register; use existing e1000_has_link() function instead.
