It still requires periph to be set in xpt_done to decide in which queue
to queue the ccb (BIO or NET).
After the changes made above the code works (and makes sense).
I suggest the following:
When using camcontrol to scan the bus, the peripheral that is used is
xpt_periph. If xpt_periph is exported in cam_periph.h that peripheral
can be used as a place holder.
