I should also add that I added ran into the periodic underruns problem
described at the bottom of the page below, but the RT_RUNTIME_SHARE solution
worked.

Hi Shane,
I've had success using DPDK with ~200Msps rates over a QSFP+ link to a USRP
N320. I still have the uhd.conf file from that project but do not have the
hardware on hand to try anything.
One difference is that my uhd.conf used only underscores, not dashes. UHD's key
matching in /host/l

Hello all,
I'm trying to configure my X310 to transmit at its full 200 MS/s rate

DPDK can't find the X310 when I try to run scripts. I can use the X310
when I don't bind the NIC
