/* ifi_flags.

   IFF_* flags.

   The only change is:
   IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
   more not changeable by user. They describe link media
   characteristics and set by device driver.

   Comments:
   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
   - If neither of these three flags are set;
     the interface is NBMA.

   - IFF_MULTICAST does not mean anything special:
   multicasts can be used on all not-NBMA links.
   IFF_MULTICAST means that this media uses special encapsulation
   for multicast frames. Apparently, all IFF_POINTOPOINT and
   IFF_BROADCAST devices are able to use multicasts too.

   For usual devices it is equal ifi_index.
   If it is a "virtual interface" (f.e. tunnel), ifi_link
   can point to real physical interface (f.e. for bandwidth calculations),
   or maybe 0, what means, that real media is unknown (usual
   for IPIP tunnels, when route to endpoint is allowed to change)
