From bc8acf2c8c3e43fcc192762a9f964b3e9a17748b Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 2 Sep 2010 13:07:41 -0700 Subject: drivers/net: avoid some skb->ip_summed initializations fresh skbs have ip_summed set to CHECKSUM_NONE (0) We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers. Introduce skb_checksum_none_assert() helper so that we keep this assertion documented in driver sources. Change most occurrences of : skb->ip_summed = CHECKSUM_NONE; by : skb_checksum_none_assert(skb); Signed-off-by: Eric Dumazet Signed-off-by: David S.
