133    IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
134    more not changeable by user. They describe link media
135    characteristics and set by device driver.
136 
137    Comments:
138    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
139    - If neither of these three flags are set;
140      the interface is NBMA.
141 
142    - IFF_MULTICAST does not mean anything special:
143    multicasts can be used on all not-NBMA links.
144    IFF_MULTICAST means that this media uses special encapsulation
145    for multicast frames. Apparently, all IFF_POINTOPOINT and
146    IFF_BROADCAST devices are able to use multicasts too.

153    or maybe 0, what means, that real media is unknown (usual
