 168   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
 169   - If neither of these three flags are set;

 171
 172   - IFF_MULTICAST does not mean anything special:
 173   multicasts can be used on all not-NBMA links.
 174   IFF_MULTICAST means that this media uses special encapsulation
 175   for multicast frames. Apparently, all IFF_POINTOPOINT and
 176   IFF_BROADCAST devices are able to use multicasts too.
