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

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