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

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