I just found a posting[1] from Archie Cobbs to freebsd-net@ where he
suggested loading the ng_ether module before running mpd(8). "That's
silly", thought I, "there's already a bunch of modules loaded
automatically".
And indeed, after an unsuccessful attempt, kldstat(8) shows the
following:
Id Refs Address Size Name
1 10 0xc0100000 1fd990 kernel
2 1 0xc02fe000 5448 vesa.ko
3 1 0xc129e000 6000 procfs.ko
4 1 0xc130c000 2000 green_saver.ko
5 1 0xc1323000 3000 ng_socket.ko
6 5 0xc172c000 9000 netgraph.ko
7 1 0xc132f000 3000 ng_iface.ko
8 1 0xc1338000 6000 ng_ppp.ko
9 1 0xc1343000 4000 ng_bpf.ko
10 1 0xc134e000 4000 ng_vjc.ko
But no ng_ether. So I loaded it with kldload(8) and tried again. And
what do you know - it worked!

I'm still puzzled as to how it uses the 'real' network interface, which
isn't even configured. And why does it load 6 ng modules, but not the
last one?
Anyway, I won't know if it really works until my provider starts routing
packets in this direction, but it certainly looks hopeful.
Thanks
Rob.
