 176   Comments:
 177   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
 178   - If neither of these three flags are set;
 179     the interface is NBMA.
 180
 181   - IFF_MULTICAST does not mean anything special:
 182   multicasts can be used on all not-NBMA links.
 183   IFF_MULTICAST means that this media uses special encapsulation
 184   for multicast frames. Apparently, all IFF_POINTOPOINT and
 185   IFF_BROADCAST devices are able to use multicasts too.
