Dear all,we have finally managed to set up UHD (3.15) with DPDK (18.11) support on our RedHat 7 system (both installed from source) with our N310. I have configured the system as explained here http://files.ettus.com/manual/page_dpdk.html but when calling
uhd_usrp_probe --args "use_dpdk=1,mgmt_addr=192.168.12.1,addr=192.168.10.2,second_addr=192.168.20.2,master_clock_rate=122.88e6,type=n3xx"
I am getting the following runtime error (all the way at the bottom):[INFO] [UHD] linux; GNU C++ version 4.8.5 20150623 (Red Hat 4.8.5-39); Boost_106900; UHD_3.15.0.0-0-g4e06022c

I am also copying the output of "dpdk-devbind --status" which shows that the two interfaces connected to the USRP use the vfio-pci driver for DPDK

What surprises me is that in the output of the uhd_usrp_probe, it does not say it is using the driver for DPDK. any ideas what could be wrong?
