A hotplug capable port is an external port, so mark it as such. We even say this ourselves in libata-scsi.c: /* set scsi removable (RMB) bit per ata bit, or if the * AHCI port says it's external (Hotplug-capable, eSATA). */ This also matches the terminology used in AHCI 1.3.1 (the keyword to search for is "externally accessible").
