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