3629 | * If val is in a valid range then set the adapter's topology field and | |
3630 | * issue a lip; if the lip fails reset the topology to the old value. | |
3631 | * | |
3632 | * If the value is not in range log a kernel error message and return an error. | |
3633 | * | |
3634 | * Returns: | |
3635 | * zero if val is in range and lip okay | |
3636 | * non-zero return value from lpfc_issue_lip() | |
3637 | * -EINVAL val out of range | |
