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

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