That was not it. That ensures that outbound MultiCast go out eth0. It can be 
over-ridden by setsockopts() IP_MULTICAST_IF but that's all outbound to the 
network.

Coming in from the network to the TS7250 should only need an IP_ADD_MEMBERSHIP 
from an INNET_ANY interface.

Curiously running a sniffer on the TS7250 which monitors all IP frames using a 
RAW socket, I don't see the inbound MultiCast frames which means they're being 
filtered either at the MAC level or, well, the MAC level.
