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