How to switch on-board (LimeSDR-Mini) loopback shunt transistor with pyLMS7002Soapy

Hello,

I have a LimeSDR-Mini connected to a laptop running Ubuntu 20.04. I have everything up and running (Lime Suite, Gnu Radio, Octave and pyLMS7002Soapy. I like python, so I mainly use pyLMS7002Soapy to communicate with the board. However, I can’t find a way to switch the on-board loopback shunt transistor with pyLMS7002Soapy. I know there are on-chip loopback paths (RF, BB and LimeLight) which I can enable via register settings of the LMS7002, but the on-board loopback path can only be switched by writing to the FPGA-registers and I can’t find a way to do that via pyLMS7002Soapy.

Not sure whether this is because SoapySDR doesn’t have an appropriate mechanism or it’s just missing from SoapyLMS7. @Garmus, what are your thoughts on this?
