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

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