Hi, I am getting a bunch of "Could not determine link speed" warnings when I run with an N310. Note that I don't get these warnings with an X310 (in the same setup). Below, you will find the output from "uhd_usrp_probe" for the N310. Is there any setting that I need to change so that MPMD can determine the link speed? Note that even though the warning mentions 1GbE, the max speed shown greatly exceeds 1GbE and in fact I am able to stream a full rates despite the warning. Rob
