93   IFF_* flags.
94
95   The only change is:
96   IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
97   more not changeable by user. They describe link media
98   characteristics and set by device driver.
99
100   Comments:
101   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
102   - If neither of these three flags are set;
103     the interface is NBMA.
104
105   - IFF_MULTICAST does not mean anything special:
106   multicasts can be used on all not-NBMA links.
107   IFF_MULTICAST means that this media uses special encapsulation
108   for multicast frames. Apparently, all IFF_POINTOPOINT and
109   IFF_BROADCAST devices are able to use multicasts too.

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