Which has led me to believe that the problem lies in how the NICs are configured. I'm working with Intel x701 NIC with the i40e driver. By any chance is this a known issue with these NICs or driver? I have tried upgrading my i40e driver to the recommended version v2.9.21 for dpdk 19.11, however that did not work. I would really appreciate help in debugging this issue. -- Archit Pandey Senior Year Undergraduate Student Department of Computer Science and Engineering National Institute of Technology Karnataka Surathkal, India On Wed, 8 Jan 2020, 10:47 pm Archit Pandey, wrote: > Hello team, > > > I'm unable to run any DPDK application due to the links bound to DPDK > being down.
