Subject: [PATCH 1/8] sky2: gigabit full duplex autonegotiate
Date: Tue, 26 Sep 2006 16:17:07 -0700 [thread overview]
Message-ID: <20060926161707.10ce4edc@freekitty> (raw)
(vger gagged on the quilt version of these patches)
Look at the registers correctly, when doing gigabit full duplex.
Need to look for link partner result.
