If there is a conflict between a request for a main command and a request for a sub-command, the drive will
process the main command request.
If the drive is currently processing a main command or a sub-command, the drive gives priority to the command
being processed. The sub-command is given priority if an INV_CTL main command and an INV_I/O sub-
command conflict.
