NAME
       mlx5dv_modify_qp_udp_sport - Modify the UDP source port of a given QP

SYNOPSIS
              #include <infiniband/mlx5dv.h>

              int mlx5dv_modify_qp_udp_sport(struct ibv_qp *qp, uint16_t udp_sport)

DESCRIPTION
       The UDP source port is used to create entropy for network routers
       (ECMP), load balancers and 802.3ad link aggregation switching that are
       not aware of RoCE IB headers.

       This API enables modifying the configured UDP source port of a given
       RC/UC QP when QP is in RTS state.

ARGUMENTS
       qp     The ibv_qp object to issue the action on.

       udp_sport
              The UDP source port to set for the QP.

RETURN VALUE
       Returns 0 on success, or the value of errno on failure (which indicates
       the failure reason).
