net: bridge: fdb: add support for fine-grained flushing
Add the ability to specify exactly which fdbs to be flushed. They are described by a new structure - net_bridge_fdb_flush_desc. Currently it can match on port/bridge ifindex, vlan id and fdb flags. It is used to describe the existing dynamic fdb flush operation. Note that this flush operation doesn't treat permanent entries in a special way (fdb_delete vs fdb_delete_local), it will delete them regardless if any port is using them, so currently it can't directly replace deletes which need to handle that case, although we can extend it later for that too.
