90 IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
91 more not changeable by user. They describe link media
92 characteristics and set by device driver.
95 - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
96 - If neither of these three flags are set;
97 the interface is NBMA.
99 - IFF_MULTICAST does not mean anything special:
100 multicasts can be used on all not-NBMA links.
101 IFF_MULTICAST means that this media uses special encapsulation
102 for multicast frames. Apparently, all IFF_POINTOPOINT and
103 IFF_BROADCAST devices are able to use multicasts too.
107 For usual devices it is equal ifi_index.
108 If it is a "virtual interface" (f.e. tunnel), ifi_link
109 can point to real physical interface (f.e. for bandwidth calculations),
110 or maybe 0, what means, that real media is unknown (usual
111 for IPIP tunnels, when route to endpoint is allowed to change)
