I've been trying unsuccessfully to get multicast working using an EtherExpressPro100 on 2.2.10. I have used the code below to test whether the multicast address is added successfully. 

The address used belongs to another machine. After installing the module, I run tcpdump -p, and filter on the packets belonging to the address just added.

Using the dec tulip, there are no problems with this, however, using the eepro100, no packets are received. I also tried the same on the 3c59x driver and found it exhibited the same problem.

Any information on how multicast on the eepro100 should work would be greatly appreciated.
