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