The series adds an ability for the bridge to function in non-promiscuous mode. We do it in 3 steps. First we add an interface to palce the switch into non-promisc mode. In this mode, all port of the switch turn promisc off and turn on IFF_ALLMULTI to continue handling multicast traffic. Second we add an ability to designate a bridge port as uplink. Third we add IFF_UNICAST_FLT support to the bridge and sync all unicast HW addresses to the uplink ports. Default bridge operation continues to remain "promiscuous". The new functionality has to be enabled via sysfs (similar to other bridge extensions). The uplink mode is implemented as a flag on a bridge port. The api to change that flag follows the existing api to enable/disable other existing flags. Changes since rfc v2: * Sync/unsync address on uplink upon the uplink flag change. This allows for uplink replacements without loss of addresses. Changes since rfc v1: * Fixed submit log * Simplifyied uplink logic. Uplink is now a flag per port. This removes the need for a separate list. * Clean-up hw list once the port has been removed.
