We have been unable to estable 100% reliable connections to an N310 USRP radio through its 10 Gbit ethernet from Linux. What happens is that it works fine for a period of time - 30 to 60 minutes, typically. Then we see a couple of U's in the output. Unfortunately, that is fatal for our application.
Using the unmodified tx_samples_from_file or one modified to use separate threads to read data from the file and to sent it over the socket to the radio, the symptoms are the same. All the evidence is that the application is sending data continuously without any delays. Also, the "network" has no devices on it except for the host computer, a high performance 10G switch, and the N310 radio. We are wondering if this could be a Linux "feature". We would like to try increasing the socket priority with SO_PRIORITY. However, we are not finding any hooks in the UHD software for this. Suggestions? Thanks!
