	My code just open a HCI socket and send HCI commands. The HCI
commands are pretty straightforward, well documented and do everything
you want, so I don't see the point in adding weird ioctls. The main
issue I have with ioctls is that they are blocking, so that's why my
code use HCI socket for everything (including Inquiry).
	Not that the main issue will be firware support. For example
the QoS feature I needed is not implemented in the CSR firmware.

	Ciao...

	Jean
