98   IFF_* flags.
99
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.

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