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

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