I am utilizing the platform_ad9361 devices from the ocpi.platform project,
and I am trying to run the FSK application. I am running into an issue
with the interfaces of the new platform data subs.

When I run the application, I get the following Exception being thrown:

  Exception thrown: Protocols in connection are incompatible: port "out" of
instance "data_src_qadc" has protocol "ComplexShortWithMetadata" vs. port
"in" of instance "dc_offset_filter" has protocol "iqstream"

While I can understand a mismatch of protocol is definitely an error and
some adapter needs to be made, I am a bit confused since I have a bit file
that is loaded and has the devices connected together, so the HDL assembly
knew how to connect them together but the software doesn't understand how
they're connected?

Note that I get the same thing with the DAC side of things as well, just
swapped iqstream and ComplexShortWithMetadata.

Do I need an adapter in here somewhere? How can I go from
ComplexShortWithMetadata over to iqstream and, subsequently, vice-versa?

Thanks,
Brian
