Enabling network_monitor will give you the functional address being used in the /proc/net/streamerN. (I'm away from the source right now, so the names may be slightly different). Multicast over token-ring can be implemented in 3 ways per the RFC, in order of preference: 1) Using a specific multicast address 2) Using a functional address 3) Using promiscuous mode Olympic supports option 2, the 3c359 would do option 1, but I never put it in as it would be the only card that would, so it supports option 2 also. ibmtr maybe option 2, but I have a suspicion it uses option 3. I believe the same code path was added to the lanstreamer driver and should work, although the lanstreamer hardware is an often bizarre world to be in and doesn't always behave as it should. When I added the token ring multicast code to the kernel and drivers, the lanstreamer driver didn't exist so I only tested with ibmtr, olympic and 3c359.
