164 IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
165 more not changeable by user. They describe link media
166 characteristics and set by device driver.
169 - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
170 - If neither of these three flags are set;
171 the interface is NBMA.
173 - IFF_MULTICAST does not mean anything special:
174 multicasts can be used on all not-NBMA links.
175 IFF_MULTICAST means that this media uses special encapsulation
176 for multicast frames. Apparently, all IFF_POINTOPOINT and
177 IFF_BROADCAST devices are able to use multicasts too.
181 For usual devices it is equal ifi_index.
182 If it is a "virtual interface" (f.e. tunnel), ifi_link
183 can point to real physical interface (f.e. for bandwidth calculations),
184 or maybe 0, what means, that real media is unknown (usual
185 for IPIP tunnels, when route to endpoint is allowed to change)
