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