[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 <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
