Excellent!!! It is less ambiguity now for me. Could you point me to
any documentation about ctl_enqueudata/clt_enqueuembuf? Is there any
sample code about using kernel control to exchange data between
kernelspace and userspace?

Too bad that the NKE documentation fails to mention these functions?


They're documented in the KPI reference:

http://developer.apple.com/documentation/Darwin/Reference/ KPI_Reference/kern_control/index.html

But you're right. They should be at least mentioned in the conceptual docs. I'll file a bug and fix this the next time I rev that document.
