NAME
       mlx5dv_devx_query_eqn - Query EQN for a given vector id.

SYNOPSIS
              #include <infiniband/mlx5dv.h>

              int mlx5dv_devx_query_eqn(struct ibv_context *context, uint32_t vector,
                                        uint32_t *eqn);

DESCRIPTION
       Query EQN for a given input vector, the EQN is needed for other device
       commands over the DEVX interface.

       The DEVX API enables direct access from the user space area to the mlx5
       device driver, the EQN information is needed for few commands such as
       CQ creation.

ARGUMENTS
       context
              RDMA device context to work on.

       vector Completion vector number.

       eqn    The device EQ number which relates to the given input vector.

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