From c3df0748ee43101dfc5c94d1f61ddfca0ff5baa4 Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Mon, 2 Nov 2009 14:27:02 +0000 Subject: tg3: 5785: Set port mode to MII when link down 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. Signed-off-by: Matt Carlson Reviewed-by: Michael Chan Signed-off-by: David S.
