- allow the user to force the TCP mss below the fail-safe 216 with a low
interface MTU.
- break a tcp_output() -> tcp_mtudisc() -> tcp_output() infinite recursion
when the TCP mss ends up larger than the interface MTU (when the if_mtu is
smaller than the tcp header). connections will still stall
feedback from itojun@, claudio@ and provos and testing from beck@
