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

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