  Modified files:
    sys/conf             files options 
    sys/netinet          tcp.h tcp_input.c tcp_output.c tcp_seq.h 
                         tcp_subr.c tcp_syncache.c tcp_timer.c 
                         tcp_var.h 
  Added files:
    sys/netinet          tcp_sack.c 
  Log:
  Add support for TCP Selective Acknowledgements.  The work for this
  originated on RELENG_4 and was ported to -CURRENT.
  
  The scoreboarding code was obtained from OpenBSD, and many
  of the remaining changes were inspired by OpenBSD, but not
  taken directly from there.
  
  You can enable/disable sack using net.inet.tcp.do_sack. You can
  also limit the number of sack holes that all senders can have in
  the scoreboard with net.inet.tcp.sackhole_limit.
