mlx5dv_create_...packet_reformat(3) mlx5dv_create_...packet_reformat(3)
mlx5dv_create_flow_action_packet_reformat - Flow action reformat
packet for mlx5 provider
#include <infiniband/mlx5dv.h>
struct ibv_flow_action *
mlx5dv_create_flow_action_packet_reformat(struct ibv_context *ctx,
size_t data_sz,
void *data,
enum mlx5dv_flow_action_packet_reformat_type reformat_type,
enum mlx5dv_flow_table_type ft_type)
Create a packet reformat flow steering action. It allows
adding/removing packet headers.
ctx
RDMA device context to create the action on.
data_sz
The size of *data* buffer.
data
A buffer which contains headers in case the actions requires them.
reformat_type
The reformat type to be create. Use enum mlx5dv_flow_action_packet_reformat_type.
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TUNNEL_TO_L2:
Decap a generic L2 tunneled packet up to inner L2.
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L2_TUNNEL:
Generic encap, data should contain the encapsulating
headers.
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L3_TUNNEL_TO_L2:
Will do decap where the inner packet starts from L3. data
should be MAC or MAC + vlan (14 or 18 bytes) to be appended
to the packet after the decap action.
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L3_TUNNEL:
Will do encap where is L2 of the original packet will not
be included. data should be the encapsulating header.
ft_type
It defines the flow table type to which the packet reformat action
will be attached.
Upon success mlx5dv_create_flow_action_packet_reformat will return
a new struct ibv_flow_action object, on error NULL will be
returned and errno will be set.
