Hi Kasim, There are some previous posts to the user's list around Feb 2-3, 2021 regarding some DPDK troubles I was having. In particular, Aaron Rossetto mentioned putting just a few symlinks in a new folder and using the dpdk_driver variable from uhd.conf to point to this folder. This may be helpful for your case. Rob
