Its the same device args, so python/c++ it shouldnt make a difference.

The driver is however testing if it can handle that MTU by sending test
packets. Perhaps its still a network configuration issue?

Also, you should be able to

uhd_usrp_probe --args="addr0=10.1.1.105, recv_frame_size=4096,
send_frame_size=4096"

and still see the same issue.
