ukSCSI user-level driver

uk* at scsibus?

The uk driver provides support for a process to address devices on the SCSI bus for which there is no configured driver.

A SCSI adapter must also be separately configured into the system before this driver makes sense.

The uk driver has no ioctls of its own but rather acts as a medium for the generic scsi(4) ioctls. These are described in ⟨sys/scsiio.h⟩.

uk{x} is the 'xth' unknown device found.

All scsi(4) debug ioctls work on uk devices.
