Not sure if this is generally applicable but I ran a test using testpmd as
a non-root user on my Ubuntu 21.04 system.

I bound a couple of ports using the i40e driver to DPDK using vfio-pci
kernel driver, and then did a chmod on the /dev/vfio/ nodes for them to
give the user access. I also gave the user rw access to the hugepage mount
point I had created. Thereafter testpmd ran fine as a non-root user and I
was able to put traffic through it.
