  89    The only change is:
  90    IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
  91    more not changeable by user. They describe link media
  92    characteristics and set by device driver.
  93
  94    Comments:
  95    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
  96    - If neither of these three flags are set;
  97      the interface is NBMA.
  98
  99    - IFF_MULTICAST does not mean anything special:
 100    multicasts can be used on all not-NBMA links.
 101    IFF_MULTICAST means that this media uses special encapsulation
 102    for multicast frames. Apparently, all IFF_POINTOPOINT and
 103    IFF_BROADCAST devices are able to use multicasts too.

 110    or maybe 0, what means, that real media is unknown (usual
 111    for IPIP tunnels, when route to endpoint is allowed to change)
