  99    IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
 100    more not changeable by user. They describe link media
 101    characteristics and set by device driver.
 102
 103    Comments:
 104    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
 105    - If neither of these three flags are set;
 106      the interface is NBMA.
 107
 108    - IFF_MULTICAST does not mean anything special:
 109    multicasts can be used on all not-NBMA links.
 110    IFF_MULTICAST means that this media uses special encapsulation
 111    for multicast frames. Apparently, all IFF_POINTOPOINT and
 112    IFF_BROADCAST devices are able to use multicasts too.

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