freebsd stable - Oct 2007 - MFC requests for 6.3

I would like to request that some useful work on networking be MFCed from
-CURRENT to -STABLE in time for the release of FreeBSD 6.3. In particular,
I'd like to see some of the Netgraph nodes which are new or which have seen
extensive development brought in -- ng_nat and ng_car in particular. Bringing
in the latest version of ng_nat would allow more flexible in-kernel NAT,
while ng_car (which doesn't seem to be in 6-STABLE at all) would allow
burstable traffic shaping -- something that DUMMYNET doesn't have. The
latest version of mpd wouldn't be fully usable unless these and other
Netgraph code that was developed for it are there....

The thing that's worried me, following only stable@freebsd.org traffic, 
were the reports about the new em driver (6.6.6?) causing hangs and other 
problems with people who have been updating RELENG_6 - have those who had 
those problems seen their issues resolved?  I've got remote boxes using em 
that I can't risk making inaccessible and can't test locally.

I'd like to add geom_multipath to the wishlist :)

Hello Brett,

ng_nat is part of 6-STABLE and maybe Alexander(mav@) would
like to bring in ng_car as well. Don't know the MFC policies
or other possible difficulties. Let him know of your request.

Most of Netgraph changes were merged to RELENG_6. ng_nat changes were
merged 3 months ago. Latest ng_car is not merged, but for FreeBSD 5-6.x
it is present as net/ng_car port.

Latest 4.3 and 5.0 mpd are able to determine actual system capabilities
at the build time. To have ng_car support on FreeBSD 5-6.x you should
install mpd from ports with setting ng_car checkbox.

The RELENG-6 version is dated from July. Has there been any newer 
work? I seem to recall that in the mpd 5 announcement there was a
mention of new work on this node.

Ah.... That's a port, not part of the base system, which is why
I didn't see it. This is good, because it would mean that it would 
work with both 6.x and 7.x.

It IS there:
