Subject: [net-2.6 PATCH] e1000e: do not initiate autonegotiation during OEM configuration
Date: Thu, 19 Nov 2009 16:17:30 -0800 [thread overview]
Message-ID: <20091120001722.29775.22407.stgit@localhost.localdomain> (raw)
From: Bruce Allan <bruce.w.allan@intel.com>
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.
