From 1bb482f8a46000f77577948ff1c350275bba7dc9 Mon Sep 17 00:00:00 2001 From: Narender Kumar Date: Sun, 23 Aug 2009 08:35:09 +0000 Subject: netxen: ethtool statistics and control for LRO Add ethtool -K knob to control LRO in firmware. LRO path is completely separated from GRO, LRO packets are still fed with netif_receive_skb(). Also fix ethtool statistics to include LRO packets. Also use correct message type while configuring interrupt coalescing. Signed-off-by: Narender Kumar Signed-off-by: Dhananjay Phadke Signed-off-by: David S.
