172 
173    - IFF_MULTICAST does not mean anything special:
174    multicasts can be used on all not-NBMA links.
175    IFF_MULTICAST means that this media uses special encapsulation
176    for multicast frames. Apparently, all IFF_POINTOPOINT and
177    IFF_BROADCAST devices are able to use multicasts too.
