testpmd: No probed ethernet devices message

I am trying to use DPDK 19.11 in centOS 8.0. I have compiled DPDK as per guidelines. Then I did bind ethernet NIC to DPDK driver and left Wifi to Linux kernel using dpdk_setup.sh.

1.When I try to use testpmd the following message is displayed. "testpmd: No probed ethernet devices" though the port is bounded.

When I try to use dpdk_pdump, I get the message EAL: Error - exiting with code: 1 Cause: No Ethernet ports - bye

Please find driver allocation

Network devices using DPDK-compatible driver

I did refer the following question DPDK run testpmd failed. EAL:no probed ethernet device.

2.If I put wifi interface also to DPDK driver whether testpmd will forward packets between two DPDK ports?

  1. We bring down NIC interface so that it can be bounded to DPDK driver. Do we need to bring it up once it's attached with DPDK using any command?

Any inputs on how do I resolve it?

The expectation of Having RTL and Wifi are incorrect. List of supported DPDK ports.
