From 818f33313caab9be2a10458500dbed4a88c1b334 Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Thu, 19 Nov 2009 14:17:30 +0000 Subject: [PATCH] e1000e: do not initiate autonegotiation during OEM configuration When configuring the OEM bits in the PHY on 82577/82578, do not restart autonegotiation if the firmware is blocking it (e.g. when an IDE-R session is active) because the link must not go down.
