Re: [PATCH] Netdump for review and testing -- preliminary version

[just don't know what namely need to test, so]

All made according to your instructions.
The only way I could trigger netdump was
to run its ddb command by hand. Neither
debug.kdb.enter nor debug.kdb.panic don't do it.

Some numbers and output (bit verbose
but again don't know what need to show here)
Entered through debug.kdb.panic, thus Panicstring.

I tried to netdump a bit later again, but it couldn't find server, which
runs though, and client traffic was seen on server-side (w/o reply).

As for netdumpserv,
it misses #include <sys/cdefs.h> before __FBSDID();
I happily tested it on 7.3-amd64.
