I've been using the dc driver without a hitch
but when I updated to current two days ago dc stopped
working.  Symptoms are no link light on the hub and
ifconfig reports <no-carrier>.  Lights are on on the
NIC though.  Enumerating the varieties of media/mediaopt
has no effect.  Fortunately, there is the de driver,
geriatric it may be, but it works.  Not one thing was
changed but the update of a just pre-ipv6 system to
current.

(Fully expecting to get the full gin-joint treatment here
 shortly :-)

Here's two snippets from messages, 1st with dc
configured and then de:

Here's the probe for dc, which doesn't work (but used to):
