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).
