[USRP-users] E310 network mode throughput

Hi Jason,

that already is pretty optimized. The architecture of the network
interface on the E310 doesn't allow for higher rates, really.
Network mode is a diagnostic tool; a lot of work has gone into getting
it to work at these rates.

Best regards,
Marcus
