mlx5dv_query_qp_lag_port - Query the lag port information of a given QP
.SH SYNOPSIS
.IP
.nf
\f[C]
#include <infiniband/mlx5dv.h>

int mlx5dv_query_qp_lag_port(struct ibv_qp *qp, uint8_t *port_num,
                 uint8_t *active_port_num);
\f[R]
.fi
.SH DESCRIPTION
.PP
This API returns the configured and active port num of a given QP in
mlx5 devices.
.PP
The active port num indicates which port that the QP sends traffic out
in a LAG configuration.
.PP
The num_lag_ports field of struct mlx5dv_context greater than 1 means
LAG is supported on this device.
.SH ARGUMENTS
.TP
\f[I]qp\f[R]
The ibv_qp object to issue the action on.
.TP
\f[I]port_num\f[R]
The configured port num of the QP.
.TP
\f[I]active_port_num\f[R]
The current port num of the QP, which may different from the configured
value because of the bonding status.
.SH RETURN VALUE
.PP
0 on success; EOPNOTSUPP if not in LAG mode, or other errno value on
other failures.
