 170    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

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