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