 169    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

 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.
