You can't ping it using the 'ping' command (as you've probably found out yourself). We don't implement this outside of UHD, but UHD sends out discovery management packets into that network to see what's on the other side (e.g., a crossbar). You could forge one of those and send it in there via UHD, but you'd have to figure out the packet format from the RFNoC spec and the source code.
