 140    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
 141    - If neither of these three flags are set;
 142      the interface is NBMA.
 143
 144    - IFF_MULTICAST does not mean anything special:
 145    multicasts can be used on all not-NBMA links.
 146    IFF_MULTICAST means that this media uses special encapsulation
 147    for multicast frames. Apparently, all IFF_POINTOPOINT and
 148    IFF_BROADCAST devices are able to use multicasts too.
