We now live in a universe where SATA SSDs are attached to SAS controllers. So the same disk can be presented as da0 or ada0. But, our 4k quirk table entries are specific to which subsystem they fall under. e.g. the same drive attached to a AHCI controller can get different quirks as when it is attached to a LSI SAS controller. My first response was to unify the quirk table, but I'm not sure what that looks like in CAM. There is a clear line between SCSI and ATA in the directory and code structure. Any thoughts on what to do here? sean
