[net-next-2.6 PATCH] e1000e: Fix for offline diag test failure at first call
From: Jeff Kirsher <hidden>
Date: 2010-10-16 03:35:52
From: Carolyn Wyborny <redacted> Move link test call to later in the offline sequence, move the restore settings block to afterwards and add another reset to ensure the hardware is in a known state afterwards.
