    [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()...
