Subject: [PATCH 09/20] tg3: 5785: Set port mode to MII when link down
Date: Mon, 2 Nov 2009 16:27:02 -0800 [thread overview]
Message-ID: <1257211999.22007@xw6200> (raw)
This patch sets the port mode to MII when the link is down for the 5785.
Setting the port mode to MII instead of GMII saves power.
