Testpmd example: - Creating a flow rule on port ID 1 to consume all traffic from port ID 0 and direct it to port ID 2: flow create 1 ingress transfer pattern port_id id is 0 / end actions port_id id 2 / end Signed-off-by: Adrien Mazarguil --- drivers/net/mlx5/mlx5_nl_flow.c | 57 +++++++++++++++++++++++++++++++++++- 1 file changed, 56 insertions(+), 1 deletion(-) diff --git a/drivers/net/mlx5/mlx5_nl_flow.c b/drivers/net/mlx5/mlx5_nl_flow.c index a45d94fae..ad7a53d36 100644 --- a/drivers/net/mlx5/mlx5_nl_flow.c +++ b/drivers/net/mlx5/mlx5_nl_flow.c @@ -36,6 +36,7 @@ enum mlx5_nl_flow_trans { ATTR, PATTERN, ITEM_VOID, + ITEM_PORT_ID, ITEM_ETH, ITEM_VLAN, ITEM_IPV4, @@ -56,7 +57,7 @@ enum mlx5_nl_flow_trans { #define TRANS(...)
