131
132   The only change is:
133   IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
134   more not changeable by user. They describe link media
135   characteristics and set by device driver.
136
137   Comments:
138   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
139   - If neither of these three flags are set;
140     the interface is NBMA.
141
142   - IFF_MULTICAST does not mean anything special:
143   multicasts can be used on all not-NBMA links.
144   IFF_MULTICAST means that this media uses special encapsulation
145   for multicast frames. Apparently, all IFF_POINTOPOINT and
146   IFF_BROADCAST devices are able to use multicasts too.

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