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

- * @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
