 173    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

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