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

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