Since i am working on GPL'd code and the results are going to be

if by precise timing you mean "exact mac time in TU/usecs when frame
was received at the radio", then you might have a _problem_.
You see, the firmware already receives fully packed frames from
the MAC processor and only _forwards_ them all [as is] in
one big DMA to the USB subsystem.
(this is done in src/wlan.c handle_rx())
So, unless the HW has a _magic_ flag to enable this capability...
you are sort of screwed :-/.
I would love this feature as well. I have a device to test if that can
help. I share the feeling of Christian however... but maybe your
documentation says something about a special flag.
