Description
mlx5dv_create_flow() creates a steering flow rule with the ability to specify specific driver properties.Arguments
Please see mlx5dv_create_flow_matcher(3) for flow_matcher and match_value.- num_actions
- Specifies how many actions are passed in actions_attr

};- type
- MLX5DV_FLOW_ACTION_DEST_IBV_QP The QP passed will receive the matched packets. MLX5DV_FLOW_ACTION_IBV_FLOW_ACTION The flow action to be applied. MLX5DV_FLOW_ACTION_TAG Flow tag to be provided in work completion. MLX5DV_FLOW_ACTION_DEST_DEVX The DEVX destination object for the matched packets. MLX5DV_FLOW_ACTION_COUNTERS_DEVX The DEVX counter object for the matched packets.
- qp
- QP passed, to be used with type MLX5DV_FLOW_ACTION_DEST_IBV_QP.
- action
- Flow action, to be used with type MLX5DV_FLOW_ACTION_IBV_FLOW_ACTION see mlx5dv_create_flow_action_modify_header(3) and mlx5dv_create_flow_action_packet_reformat(3).
- tag_value
- tag value to be passed in the work completion, to be used with type MLX5DV_FLOW_ACTION_TAG see ibv_create_cq_ex(3).
- obj
- DEVX object, to be used with type MLX5DV_FLOW_ACTION_DEST_DEVX or by MLX5DV_FLOW_ACTION_COUNTERS_DEVX.
