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

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