NAME

mlx5dv_query_qp_lag_port - Query the lag port information of a given QP


#include <infiniband/mlx5dv.h>

int mlx5dv_query_qp_lag_port(struct ibv_qp *qp, uint8_t *port_num,
                 uint8_t *active_port_num);

This API returns the configured and active port num of a given QP in mlx5 devices.

The active port num indicates which port that the QP sends traffic out in a LAG configuration.

The num_lag_ports field of struct mlx5dv_context greater than 1 means LAG is supported on this device.

qp: The ibv_qp object to issue the action on.
port_num: The configured port num of the QP.
active_port_num: The current port num of the QP, which may different from the configured value because of the bonding status.

0 on success; EOPNOTSUPP if not in LAG mode, or other errno value on other failures.
