DragonFlyBSD

Hi all,

I have this sitting around in my tree for a while and decided to catch
up with current network changes that have been going on lately. Not
all netgraph7 modules are available yet, but work is slowly in
progress. Please note that this is not tested other that it compiles
and does not deadlock. My idea is to port a sufficient number of
modules in order to get mpd5 working and test it from there. But if
anyone knows a test case to try each netgraph module individually, I
would very much appreciate to learn it.

I would like to submit this and request for comments, specially with
regards to locking and the general approach. The work is here:
http://gitweb.dragonflybsd.org/~nant/dragonfly.git/shortlog/refs/heads/netgraph7

The kernel parts are compiled in with the "options NETGRAPH7" kernel
option. The userland part (libnetgraph7) is compiled in when the
WANT_NETGRAPH7 make variable is defined.

Many thanks,
Nuno
