 177    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

 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.
