Problem with dc interface on 5.1-CURRENT

Hi Everyone,

I'm currently having a problem with the dc interfaces on a Netra in
5.1-CURRENT.  I'm able to bring the interfaces up and set their MAC
addresses.  When I do bring them up, though, I get the following:

# ifconfig dc0 up
dc0: failed to force tx and rx to idle state
dc0: failed to force tx and rx to idle state

I don't think that's a problem all by itself, but it doesn't appear that
there's any traffic going through the interface.  Trying to ping my
workstation from the Netra, and running tcpdump on the workstation shows
absolutely nothing coming from the Netra.

Anyone have advice on what I could possibly have wrong here?
