I have changed recv_ frame_size and send frame by typing uhd_usrp_probe
“addr0=126.96.36.199,recv_frame_size=4096, send:frame_size=4096”. I have
also change the MTU size on my host computer to 4096. After starting
gnuradio companion the frame size was set to 1472 bytes again. What is
hier the problem? How can I change the frame sizes permanently?
