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

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