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