| ADSL router

FWIW, with the same machine, if I do the following:

Router ---- [10baseT] --- switch --- "in"

with net.inet.ip.forwarding=1 and default routes from "in" to the
NetBSD box, with the NetBSD box defaulting to the ADSL router,
ALTQ works perfectly, and there is no data corruption, with either
ex(4) NIC.

I think this is a debugging point, rather than a workaround.  :-(

I can't see anywhere obvious in the bridging code that looks like
it might corrupt ethernet frames.  :-(
