Jonathan T. Looney 4527476029 Currently, when tcp_input() receives a packet on a session that matches a 
TCPCB, it checks (so->so_options & SO_ACCEPTCONN) to determine whether or
not the socket is a listening socket. However, this causes the code to
access a different cacheline. If we first check if the socket is in the
LISTEN state, we can avoid accessing so->so_options when processing packets
received for ESTABLISHED sessions.

If INVARIANTS is defined, the code still needs to access both variables to
check that so->so_options is consistent with the state.
