[PATCH] bonding: Add priv_flag to avoid event mishandling
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.
