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.
106 - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
107 - If neither of these three flags are set;
108 the interface is NBMA.
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.
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)
