From 0d0b16727f24f8258eeb33818347ca0f4557f982 Mon Sep 17 00:00:00 2001 From: Michał Mirosław <mirq-linux@rere.qmqm.pl> Date: Tue, 14 Dec 2010 15:24:08 +0000 Subject: net: Fix drivers advertising HW_CSUM feature to use csum_start MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some drivers are using skb_transport_offset(skb) instead of skb->csum_start for NETIF_F_HW_CSUM offload. This does not matter now, but if someone implements checksumming of encapsulated packets then this will break silently. TSO output paths are left as they are, since they are for IP+TCP only (might be worth converting though). Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S.
