Add priv_flag to specifically identify bonding-involved devices. Needed because IFF_MASTER is an unreliable identifier (vlan interfaces above bonding will inherit IFF_MASTER). Misidentification of devices would cause notifier events for other devices to be erroneously processed by bonding, causing various havoc. Bug discovered by Martin Papik <martin.papik@ipsec.info>; this patch is modified from his original.

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.
