IFF_* flags.
|

The only change is:
|
|
IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
|
|
more not changeable by user. They describe link media
|
|
characteristics and set by device driver.
|
|
|
|
Comments:
|
|
- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
|
|
- If neither 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

can point to real physical interface (f.e. for bandwidth calculations),
|
|
or maybe 0, what means, that real media is unknown (usual
|
|
for IPIP tunnels, when route to endpoint is allowed to change)
