From 86ca9db794a285f18f31ed15601696b238ccb57a Mon Sep 17 00:00:00 2001 From: Scott Feldman Date: Fri, 21 Nov 2008 21:26:55 -0800 Subject: enic: enable ethtool LRO support Enable ethtool support for get/set_flags so LRO can be turned on/off by fwding drivers such as the bridge driver. LRO is not compatible with fwding drivers. Signed-off-by: Scott Feldman Signed-off-by: David S.
