What is zyStackingSlotInfoFirmwareVersionFlash1?

This read-only octet string reports the firmware version stored in the first flash bank of a given stacking slot's unit. Admins reference this alongside the running and flash2 versions to understand what firmware images are available for that unit, useful for planning a rollback if the running version has issues. For example, confirming flash1 holds a known-stable prior firmware version gives the admin a fallback option before attempting a risky firmware upgrade on that unit.
