This patch will always keep the card in promiscuous mode.  There is
always at least one group membership (224.0.0.1) on any given interface.

Doesn't FIL_GROUP mean "receive multicasts"?  I was under the impression
that the code in the driver didn't keep track of multicast membership
because 3com cards don't have multicast group filters; their level of
multicast granularity is "on" or "off".  (This dates back from the days
of VME boards for Sun3's... and they still haven't learned... sigh)
