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