I haven't tried it yet, but have you looked at this blog post (I //think// it 
is still relevant today)?

Subject: [USRP-users] RFNoC RX -> TX loopback

Hello all,
Quick question on a RX -> TX loopback application. Say I have a rfnoc graph 
that has been connected as Radio RX -> processing block -> Radio TX so there is 
no data samples streaming to/from the host. Can I just issue the "start 
streaming" command to the Radio block itself or do I need to use a
uhd::rx_streamer to issue the command? Is there any other gotcha that I am 
overlooking?
Thanks,
Ryan
