90a05fec98 Tidied up various comments. Use the function entry macros from asm.h for 
all entry points and don't bother profiling cpu_reset().
Flush the I and D TLB's after turning the MMU and cache off in cpu_reset().

f4c5b8f91a Define profiling and non-profiling versions of the ENTRY and ASENTRY 
macros. No extra profiling code is generated if profiling is turned
on yet, but get the structure ready. (from cgd).

f9463514bf 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.

1b176d9395 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.

2da6c91259 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
(active open) or SYN,ACK (passive open) was retransmitted, the initial
congestion window for the first slow start of that connection must be
one segment.

b80d5a851b 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>.
