          <br>
          I'm studying DPDK and trying to create a simple application,
          however it <br>
          can't see a NIC bound to DPDK.<br>
          <br>
          1. Here is a list of network devices I have on my machine<br>
          <br>
          $ dpdk-devbind.py --status-dev net<br>
          <br>
          Network devices using kernel driver<br>
          ===================================<br>
          0000:01:00.0 'RTL8111/8168/8411 PCI Express Gigabit Ethernet
          Controller <br>
          8168' if=enp1s0 drv=r8169 unused=vfio-pci *Active*<br>
          0000:02:00.0 'RTL8822BE 802.11a/b/g/n/ac WiFi adapter b822'
          if=wlp2s0 <br>
          drv=rtw_8822be unused=rtw88_8822be,vfio-pci *Active*<br>
          <br>
          2. I disable my ethernet NIC (it can't be bound to DPDK while
          it is <br>
          active) and bind it to vfio-pci driver successfully<br>
          <br>
          $ ip link set enp1s0 down<br>
          $ dpdk-devbind.py -b vfio-pci enp1s0<br>
          <br>
          3. Now dpdk-devbind.py shows that the NIC is using
          DPDK-compatible driver<br>
          <br>
          $ dpdk-devbind.py --status-dev net<br>
          <br>
          Network devices using DPDK-compatible driver<br>
          ============================================<br>
          0000:01:00.0 'RTL8111/8168/8411 PCI Express Gigabit Ethernet
          Controller <br>
          8168' drv=vfio-pci unused=r8169<br>
          <br>
          Network devices using kernel driver<br>
          ===================================<br>
          0000:02:00.0 'RTL8822BE 802.11a/b/g/n/ac WiFi adapter b822'
          if=wlp2s0 <br>
          drv=rtw_8822be unused=rtw88_8822be,vfio-pci *Active*<br>
          <br>
          4. However when I run any example DPDK application it says
          that there <br>
          are no available NIC ports. For instance I wrote a simple
          application<br>
          <br>
          int main(int argc, char *argv[])<br>
          {<br>
               int ret;<br>
               int total_ports, avail_ports;<br>
          <br>
               ret = rte_eal_init(argc, argv);<br>
               if( ret < 0 )<br>
                   rte_exit(EXIT_FAILURE, "EAL initialization
          failed\n");<br>
          <br>
               total_ports = rte_eth_dev_count_total();<br>
               avail_ports = rte_eth_dev_count_avail();<br>
               printf("ETH PORTS %d %d\n", total_ports, avail_ports);<br>
          <br>
               rte_eal_cleanup();<br>
          <br>
               return 0;<br>
          }<br>
          <br>
          and both rte_eth_dev_count_total() and
          rte_eth_dev_count_avail() return 0.<br>
          <br>
          What am I doing wrong?<br>
