What is smBootRomVpdSwitchSubType?

This enumerated INTEGER (unknown, ethernet, fibre, infiniband, sas, and other values) indicates the subtype of switch module installed, as reported by the module's boot ROM firmware. An admin compares this against the switch subtype reported by the module's other firmware layer to confirm both layers agree on what kind of module is physically installed, since a mismatch can indicate a firmware corruption or a card that was swapped without a matching firmware reload. For example, if smBootRomVpdSwitchSubType still reports ethernet(1) while smMainAppVpdSwitchSubType now reports fibre(2) after a card swap, the admin knows the boot ROM firmware hasn't yet been refreshed to recognize the new Fibre Channel module.
