- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

- IFF_MULTICAST does not mean anything special:

multicasts can be used on all not-NBMA links.

IFF_MULTICAST means that this media uses special encapsulation

for multicast frames. Apparently, all IFF_POINTOPOINT and

IFF_BROADCAST devices are able to use multicasts too.
