I think the "ISOC alternate setting" are USB specific, so I think work
should be contained in hci_usb, and not require core modifications.
To this end, I think it would be helpful to separate INT and BULK
traffic from SCO traffic.
SCO is realtime, INT and BULK are not, so they require different buffer
handling.
To this end, INT and BULK work well with queues, and SCO are better
suited to ring buffers.
