From 7d3cabbcc86f7f69c47cb20c23ee84350ae6cfbb Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Wed, 1 Jul 2009 13:29:08 +0000 Subject: e1000e: disable K1 at 1000Mbps for 82577/82578 This workaround is required for an issue in hardware where noise on the interconnect between the MAC and PHY could be generated by a lower power mode (K1) at 1000Mbps resulting in bad packets. Disable K1 while at 1000 Mbps but keep it enabled for 10/100Mbps and when the cable is disconnected. Signed-off-by: Bruce Allan Signed-off-by: Jeff Kirsher Signed-off-by: David S.
