net/mlx5: Bridge, handle FDB events
Hardware supported by mlx5 driver doesn't provide learning and requires the driver to emulate all switch-like behavior in software. As such, all packets by default go through miss path, appear on representor and get to software bridge, if it is the upper device of the representor. This causes bridge to process packet in software, learn the MAC address to FDB and send SWITCHDEV_FDB_ADD_TO_DEVICE event to all subscribers. In order to offload FDB entries in mlx5, register switchdev notifier callback and implement support for both 'added_by_user' and dynamic FDB entry SWITCHDEV_FDB_ADD_TO_DEVICE events asynchronously using new mlx5_esw_bridge_offloads->wq ordered workqueue. In workqueue callback offload the ingress rule (matching FDB entry MAC as packet source MAC) and egress table rule (matching FDB entry MAC as destination MAC). For ingress table rule also match source vport to ensure that only traffic coming from expected bridge port is matched by offloaded rule. Save all the relevant FDB entry data in struct mlx5_esw_bridge_fdb_entry instance and insert the instance in new mlx5_esw_bridge->fdb_list list (for traversing all entries by software ageing implementation in following patch) and in new mlx5_esw_bridge->fdb_ht hash table for fast retrieval. Notify the bridge that FDB entry has been offloaded by sending SWITCHDEV_FDB_OFFLOADED notification. Delete FDB entry on reception of SWITCHDEV_FDB_DEL_TO_DEVICE event.
