What is rlPhdUnitGenParamFirmwareVersion?

Like the neighboring rlPhdUnitGenParamSoftwareVersion field, this object's description text is mislabeled 'Serial number of the product' in the source MIB, but its name identifies it as the unit's firmware version string. An admin distinguishes this from the software version field when a device separates boot-level code from the main software image, checking this to confirm firmware is current before a software upgrade. For example, before attempting a software upgrade, the admin checks this field to verify the unit's firmware is already at a version compatible with the new software image.
