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.
