All (or most) procesing will be done outside the 82xx. The main
purpose of the 82xx will be to do a simple conversion to/from
RTP - since the external DSP will not use this format.

The alignment concerns you mention I expect can be addressed
we anyway have to develop a driver for the DSP connected to the FCC.
The buffer management needs a second thought.

But I still do not see how the two drivers can 'communicate',
or what other requirements is put on the driver that communicate
with the DSP.
