Implement Congestion Window Monitoring as described in the TCPIMPL
...
meeting of IETF #41 by Amy Hughes <ahughes@isi.edu>, and in an upcoming
internet draft from Hughes, Touch, and Heidemann.
CWM eliminates line-rate bursts after idle periods by counting pending
(unacknowledged) packets and limiting the congestion window to the
initial congestion window plus the pending packet count. This has the
effect of allowing us to use the window as long as we continue to transmit,
but as soon as we stop transmitting, we go back to a slow-start (also known
as `use it or lose it').
This is not enabled by default. You can enable this behavior by patching
the "tcp_cwm" global (set it to non-zero) or by building a kernel with the
TCP_CWM option.

Back out a change made some time ago, that would cause the NetBSD TCP
...
to ACK immediately any packet that arrived with PSH set. This breaks
delayed ACKs in a few specific common cases that delayed ACKs were
supposed to help, and ends up not making much (if any) difference in
the case where where this ACK-on-PSH change was supposed to help.
Per discussion with several members of the TCPIMPL and TCPSAT IETF
working groups.

Fix a potential-congestion case in the larger initial congestion window

code, as clarified in the TCPIMPL WG meeting at IETF #41 : If the SYN

one segment.

Rearrange the conditions checked regarding the inclusions for <sys/types.h>

and <sys/ttydefaults.h>. Actually, one might argue about the inclusion of the
former, since the X/Open synopsis of tcgetsid() states that <termios.h> is
the only header file required, but the <termios.h> definition neither mandates
the definition of pid_t nor permits the inclusion of <sys/types.h>.
