IFF_* flags.
The only change is:

more not changeable by user. They describe link media
characteristics and set by device driver.
Comments:
- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
- If neiher of these three flags are set;
the interface is NBMA.
- 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.

For usual devices it is equal ifi_index.
If it is a "virtual interface" (f.e. tunnel), ifi_link

for IPIP tunnels, when route to endpoint is allowed to change)
