There is no such. I'm implementing IGMP snooping extensions in ng_bridge
and luckily, they are based on IPv4 addresses, so I can probably
temporarly disable preliminary {multi/other}cast discrimination based on
ethernet address and stick to IPv4 until bug is fixed. In a meantime,
I'll try to figure out some different hardware configuration to make
sure this is not "feature" of VMWare, even everything worked fine until
now.
