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) Bill
