From a7eea416cb08a514f94c0ca5ff30c18783fab054 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 11 Jun 2015 09:15:15 -0700 Subject: tcp: reserve tcp_skb_mss() to tcp stack tcp_gso_segment() and tcp_gro_receive() are not strictly part of TCP stack. They should not assume tcp_skb_mss(skb) is in fact skb_shinfo(skb)->gso_size. This will allow us to change tcp_skb_mss() in following patches. Signed-off-by: Eric Dumazet Signed-off-by: David S.
