Indeed it did.

Is there any way to issue multiple CCBs when I'm in XXstart?
Currently I'm running the 'get_addr' command but would like to issue the
'add_proto' commands to enable IP etc (though the NetBSD driver adds
protocols in the if IOCTL routine which I suppose I could do as well.
Any reason I might see a panic in cam_periph_getccb() when called from
XXregister()? (Actually the panic was in tsleep()). I attribute this to
the device not actually having completed the XXregister routine and
returning CAM_REQ_CMP. Is this the case?
I'm not sure I completly understand the role of XXstart and XXdone. Am I
to understand that all CCBs are dispatched and completed via these
routines?
Thanks.
