Update of /cvsroot/src/sys/netinet
In directory netbsd1:/var/slash-tmp/cvs-serv6941

Modified Files:
        tcp_input.c tcp_output.c tcp_subr.c tcp_var.h 
Log Message:
Fix several annoyances related to MSS handling in BSD TCP:
- Don't overload t_maxseg.  Previous behavior was to set it to the min
  of the peer's advertised MSS, our advertised MSS, and tcp_mssdflt
  (for non-local networks).  This breaks PMTU discovery running on
  either host.  Instead, remember the MSS we advertise, and use it
  as appropriate (in silly window avoidance).
- Per last bullet, split tcp_mss() into several functions for handling
  MSS (ours and peer's), and performing various tasks when a connection
  becomes ESTABLISHED.
- Introduce a new function, tcp_segsize(), which computes the max size
  for every segment transmitted in tcp_output().  This will eventually
  be used to hook in PMTU discovery.
