 * lpfc_sriov_nr_virtfn_init - Set the initial sr-iov virtual function enable

 * @phba: lpfc_hba pointer.

 * @val: link speed value.

 *

 * Description:

 * If val is in a valid range [0,255], then set the adapter's initial

 * cfg_sriov_nr_virtfn field. If it's greater than the maximum, the maximum

 * number shall be used instead. It will be up to the driver's probe_one

 * routine to determine whether the device's SR-IOV is supported or not.

 *

 * Returns:

 * zero if val saved.

 * -EINVAL val out of range
