NAME

       mlx5dv_query_qp_lag_port - Query the lag port information of a given QP

SYNOPSIS

              #include <infiniband/mlx5dv.h>

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

DESCRIPTION

       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.

ARGUMENTS

       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 bond‐
              ing status.

RETURN VALUE

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