does bridging work in -current ?

[Reid Linnemann]

I hade used the kernel bridge interface in -current several months ago,
and it did work - though it took some fiddling. IIRC, the config sysctl
parsing didn't exactly match what was described in the manpage - try
'sysctl net.link.ether.bridge.config="nt3 nt7"'. Again, IIRC this
solved my problems.
