Answering myself partially, I see there is a concept of Remote Streaming: https://uhd.readthedocs.io/en/latest/page_stream.html#stream_remote
The example goes over how to set it up for RX streams, but not for TX streams. Is it not required for that direction since the USRP is sensitive to all packets destined for its address? I assume the application on the receiving side just opens the UDP port and uses the uhd::utils::chdr::chdr_packet class to dissect or create the packet that just gets sent over the socket? Lastly, the example uses MultiUSRP - is it all the same for an RFNoC implementation? Create the graph, commit it, issue the command? Using the chdr_packet class, is there a way to know the endpoint ID to put into the header for the TX side of things? Is that fixed and something I could see from uhd_usrp_probe --tree? Sorry for all the questions, I appreciate any insights.
