Hi All,

Previously, I had DPDK-19.11 working fine on my server system, which runs
on Ubuntu 18.04.
Have a 4-Port 10 Gigabit Network card, with ports bound to use VFIO-PCI
driver.
But had to move to DPDK-20.11, and running into issues.

I installed on DPDK-20.11 on the server to /usr/local.

And did binding of ports using the dpdk-devbind script to use VFIO-PCI
driver.

But when running DPDK sample application such as->
dpdk-20.11/examples/packet_ordering,
noticed DPDK is NOT able to detect any available ports.
Getting error->  Cause: Error: no ethernet ports detected

Also when I pass parameter to block certain interfaces(Bus:Device.Function)
on a NIC, EAL throws an
Error-> EAL: failed to parse device "0000:31.00.0"

On the same system, using the same 10 Gigbit Network card, DPDK sample
applications were
working fine with older version of DPDK->19.11

Below, I have the output of commands:

~/dpdk-20.11$ sudo ./usertools/dpdk-devbind.py --status
