If `SOFTWARE_SSTEP' is defined then kgdb_stub.c needs the single-step
...
emulation in db_run.c:
- re-arrange `db_*_single_step()' and `db_*_temp_breakpoint()' -
which are only used in the `SOFTWARE_SSTEP' case - so these
are available to the KGDB code.
- make other code in db_run.c conditional on `DDB'.

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.

the definition of pid_t nor permits the inclusion of <sys/types.h>.
