From bee9e58c9e98972ac48e9748e7b89bb25dc98051 Mon Sep 17 00:00:00 2001 From: Wu Jiajun-B06378 Date: Mon, 21 May 2012 23:00:48 +0000 Subject: [PATCH] gianfar:don't add FCB length to hard_header_len FCB(Frame Control Block) isn't the part of netdev hard header. Add FCB to hard_header_len will make GRO fail at MAC comparision stage. Signed-off-by: Jiajun Wu Signed-off-by: David S.
