![]() Create new files bridge.{c|h} in en/rep directory that implement bridge interaction with representor netdevices and handle required events/notifications, bridge.{c|h} in esw directory that implement all necessary eswitch offloading infrastructure and works on vport/eswitch level. Provide new kconfig MLX5_BRIDGE which is automatically selected when both kernel bridge and mlx5 eswitch configs are enabled. Provide basic infrastructure for bridge offloads: - struct mlx5_esw_bridge_offloads - per-eswitch bridge offload structure that encapsulates generic bridge-offloads data (notifier blocks, ingress flow table/group, etc.) that is created/deleted on enable/disable eswitch offloads. - struct mlx5_esw_bridge - per-bridge structure that encapsulates per-bridge data (reference counter, FDB, egress flow table/group, etc.) that is created when first eswitch represetor is attached to new bridge and deleted when last representor is removed from the bridge as a result of NETDEV_CHANGEUPPER event. The bridge tables are created with new priority FDB_BR_OFFLOAD in FDB namespace. The new priority is between tc-miss and slow path priorities. Priority consist of two levels: the ingress table that is global per eswitch and matches incoming packets by src_mac/vid and redirects them to next level (egress table) that is chosen according to ingress port bridge membership and matches on dst_mac/vid in order to redirect packet to vport according to the following diagram: + | +---------v----------+ | | | FDB_TC_OFFLOAD | | | +---------+----------+ | | +---------v----------+ | | | FDB_FT_OFFLOAD | | | +---------+----------+ | | +---------v----------+ | | | FDB_TC_MISS | | | +---------+----------+ | +--------------------------------------+ | | | | +------+ | | | | | +------v--------+ FDB_BR_OFFLOAD | | | INGRESS_TABLE | | | +------+---+----+ | | | | match | | | +---------+ | | | | | +-------+ | | +-------v-------+ match | | | | | | EGRESS_TABLE +------------> vport | | | +-------+-------+ | | | | | | | +-------+ | | miss | | | +------+------+ | | | | +--------------------------------------+ | | +---------v----------+ | | | FDB_SLOW_PATH | | | +---------+----------+ | v Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Reviewed-by: Jianbo Liu <jianbol@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> |
