133 IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
134 more not changeable by user. They describe link media
135 characteristics and set by device driver.
138 - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
139 - If neither of these three flags are set;
140 the interface is NBMA.
142 - IFF_MULTICAST does not mean anything special:
143 multicasts can be used on all not-NBMA links.
144 IFF_MULTICAST means that this media uses special encapsulation
145 for multicast frames. Apparently, all IFF_POINTOPOINT and
146 IFF_BROADCAST devices are able to use multicasts too.
150 For usual devices it is equal ifi_index.
151 If it is a "virtual interface" (f.e. tunnel), ifi_link
152 can point to real physical interface (f.e. for bandwidth calculations),
153 or maybe 0, what means, that real media is unknown (usual
154 for IPIP tunnels, when route to endpoint is allowed to change)
