From ab6a5bb6b28a970104a34f0f6959b73cf61bdc72 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sun, 18 Mar 2007 17:43:48 -0700 Subject: [TCP]: Introduce tcp_hdrlen() and tcp_optlen() The ip_hdrlen() buddy, created to reduce the number of skb->h.th-> uses and to avoid the longer, open coded equivalent. Ditched a no-op in bnx2 in the process. I wonder if we should have a BUG_ON(skb->h.th->doff < 5) in tcp_optlen()... Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: David S.
