Hello,

I am learning DPDK.

I am using the following network cards that support dpdk.
https://www.broadcom.com/products/ethernet-connectivity/network-adapters/100gb-nic-ocp/p2100g

I am seeing rte_eth_dev_count_avail is failing. code is as follows:

====================================
nb_ports = rte_eth_dev_count_avail();
        if( nb_ports < 2 || ( nb_ports & 1 ) )
                rte_exit( EXIT_FAILURE, "Error: %u number of ports must be
even\n", nb_ports );
====================================

I have one card and just because it is for learning purposes, I have looped
back both the slots of the same cards so that I can send on one slot and
receive on another slot.

Can someone please help me how to fix the issue.

Device Driver is bnxt_en
Platform is Ubuntu 22.04

Please let me know if any more information is required.

Thanks & Regards
