Got further in getting UHD DPDK set up - to get past the UHD compilation required setting up the DPDK configuration file and installing to /usr/local/ CONFIG_RTE_BUILD_SHARED_LIB=y sudo make install DESTDIR=/usr/local T=x86_64-native-linuxapp-gcc -j60
However, UHD is not able to gain access to the device. I am guessing that I don't have DPDK set up correctly, or my processor doesn't support some required features. uhd_rx_cfile -r 100000000 -N 100000000 -f 915000000 --args="addr=192.168.93.2,use_dpdk=1" tmp [INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_3.14.1.1-3-g6a11a141 EAL: Detected 60 lcore(s) EAL: Probing VFIO support...
