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