135   The only change is:
136   IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
137   more not changeable by user. They describe link media
138   characteristics and set by device driver.
139
140   Comments:
141   - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
142   - If neither of these three flags are set;
143     the interface is NBMA.
144
145   - IFF_MULTICAST does not mean anything special:
146   multicasts can be used on all not-NBMA links.
147   IFF_MULTICAST means that this media uses special encapsulation
148   for multicast frames. Apparently, all IFF_POINTOPOINT and
149   IFF_BROADCAST devices are able to use multicasts too.
