after reading the code, iiuc, sean's work provides
nice infrastructure for ib_multicast group join/leave.
i was thinking about one more level up, i.e. generic
_net_ multicast join/leave infrastructure.  i'm not
sure exactly how it would go -- but i think all the ib
net_devices are going to need a way to associate a
multicast hw addr w/ a live mgid.  if that could be
broken out, we could all share it...
