[dpdk-users] Cannot set link up after binding with igb_uio

[Archit Pandey]

Hello team,

Weirdly this issue gets resolved upon resetting the NICs. 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.
