The current USRP API does not support receiving complex signal (I on RXA

In the future, the USRP API will support complex samples, and
"usrp_dual_source_x" will have an option called antenna: "RXAB"
Any word on this from developers?
We've talked about this in the past. The quickest way to do this would
be to mod the LFRX code. Currently it has 2 subdevices, one for the A
input and one for the B input, which control the mux settings. If we
made a setting for a "C" input which just changed the mux settings, that
would solve it pretty quickly.
