I have one more observation here.
After &qu= ot;$ sudo dpdk-devbind.py -b vfio-pci 83:00.0 83:00.1"

<= /div>
Cards are shutting down. ifconfig is not showing the cards. reins= ert of sfp is also not bringing the cards up. I had to restart the server. = Not sure why the cards are going down.

Thanks & Regards

Based on the compilation command shared it looks like you are using the bui= ld in shared library mode ` gcc main.c -g `pkg-config --cflags libdpdk --li= bs libdpdk`
Hence in EAL PCIe probe, the BNXT PMD is not triggered to identify the NIC.=

Solutions for these can be
1. Build with static library ` gcc main.c -g `pkg-config --cflags libdpdk -= -libs --static libdpdk`
2. pass the bxnt_en PMD shared library to eal args by ` sudo ./a.out -l 1 -= d librte_net_bnxt.so`

Can you try any of the above ?
