That's a good point, I'll look into making it more modular.

I have made an attempt at splitting up meta-ettus more into separate layers,
the result of that is on github (master). I was hesitant to push it public since
in it current form E31x does not work. N310 will move over to that (and the sumo
release with the next release).

Personally having the uhd recipe in meta-sdr was not convenient and we ended up
building most of the filesystems with bbappends to the UHD recipe
anyways, so I've
decided to host the UHD recipe in meta-ettus in a meta-ettus-core sublayer.

With upcoming products I hope the modularization makes sense and helps keeping
changes separate while not reinventing the wheel every time.

We are/were already working on that. Thanks for your input.
