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