 175   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

 178
 179   - IFF_MULTICAST does not mean anything special:
 180   multicasts can be used on all not-NBMA links.
 181   IFF_MULTICAST means that this media uses special encapsulation
 182   for multicast frames. Apparently, all IFF_POINTOPOINT and
 183   IFF_BROADCAST devices are able to use multicasts too.
