With automatic TCP send socket buffers we can start with a small buffer

Any testers, especially with busy FTP servers, are very welcome.
A RELENG_6 version (for FreeBSD 6.x) of the patch is here:

Just apply this patch and recompile your kernel. It is activated by
default.
Be aware that all socket buffer sizing events get logged to syslog under
LOG_DEBUG. This may affect overall system performance and you may want
to
disable logging to disk of this in syslogd.conf.
Is this relate with net.inet.tcp.sendspace? I reset my sysctl config back
to default that was for wine+utorrent, so tested with wine+utorrent on
today (Nov 25th) RELENG_6 and works fine so far.

A bit off point, I have to setup this below in sysctl to get wine+utorrent
download/upload very fast and ustable without hog the CPU.
kern.ipc.maxsockbuf=2097152
net.inet.tcp.recvspace=262144
net.inet.tcp.sendspace=262144
Cheers,
