DPDK however shows the interface as attached. I also have the KNI module present added to the system, as there are some previous threads that suggested that the interface does not show up because igb_uio driver does not generate netdev devices. Following is the log of the operations: 1. `ifconfig` before binding: enp3s0f0: flags=4099 mtu 1500 ether a0:36:9f:2d:d9:90 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 142934 bytes 63512875 (63.5 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 142934 bytes 63512875 (63.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 2. ./dpdk-devbind.py --status-dev net Network devices using kernel driver =================================== 0000:02:00.0 '82576 Gigabit Network Connection 10c9' if=enp2s0f0 drv=igb unused=igb_uio 0000:02:00.1 '82576 Gigabit Network Connection 10c9' if=enp2s0f1 drv=igb unused=igb_uio 0000:03:00.0 'Ethernet Controller 10-Gigabit X540-AT2 1528' if=enp3s0f0 drv=ixgbe unused=igb_uio 3. ./dpdk-devbind.py -b igb_uio 0000:03:00.0 4. ./dpdk-devbind.py --status-dev net Network devices using DPDK-compatible driver ============================================ 0000:03:00.0 'Ethernet Controller 10-Gigabit X540-AT2 1528' drv=igb_uio unused=ixgbe Network devices using kernel driver =================================== 0000:02:00.0 '82576 Gigabit Network Connection 10c9' if=enp2s0f0 drv=igb unused=igb_uio 0000:02:00.1 '82576 Gigabit Network Connection 10c9' if=enp2s0f1 drv=igb unused=igb_uio 5. `ifconfig` after binding: lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 142934 bytes 63512875 (63.5 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 142934 bytes 63512875 (63.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Any help will be greatly appreciated.
