Dear All I have a setup with Intel 82576 DPDK NIC. For one of the available DPDK ports i have created 8 VFs using igb_uio based on steps presented in programmers guide. Some of them are attached to VM, some maybe used on host
After some tests with l2fwd application i found out that it is not working for PF, but works perfectly for any VF (both on host and in VM). I'm still trying to find root cause of this issue but maybe someone encountered such problem Thanks in advance Tomasz Kasowicz Setup: Intel(R) Xeon(R) CPU E31220 @ 3.10GHz running Ubuntu 12.04 LTS pci_unbind.py --status Network devices using IGB_UIO driver ==================================== 0000:01:00.1 '82576NS Gigabit Network Connection' drv=igb_uio unused=igb 0000:02:11.1 '82576 Virtual Function' drv=igb_uio unused=igbvf Network devices using kernel driver =================================== 0000:00:19.0 '82579LM Gigabit Network Connection' if=eth1 drv=e1000e unused= *Active* 0000:01:00.0 '82576NS Gigabit Network Connection' if=eth0 drv=igb unused=igb_uio *Active* 0000:02:10.1 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:02:10.3 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:02:10.5 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:02:10.7 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:02:11.3 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:02:11.5 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:02:11.7 '82576 Virtual Function' if= drv=pci-stub unused=igbvf,igb_uio 0000:04:00.0 '82574L Gigabit Network Connection' if=eth3 drv=e1000e unused=igb_uio Other network devices ===================== <none> cat /sys/bus/pci/devices/0000\:01\:00.1/max_vfs 8 ls -alrt /sys/bus/pci/devices/0000\:01\:00.1/virtfn* lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn7 -> ../0000:02:11.7 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn6 -> ../0000:02:11.5 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn5 -> ../0000:02:11.3 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn4 -> ../0000:02:11.1 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn3 -> ../0000:02:10.7 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn2 -> ../0000:02:10.5 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn1 -> ../0000:02:10.3 lrwxrwxrwx 1 root root 0 Apr 9 12:09 /sys/bus/pci/devices/0000:01:00.1/virtfn0 -> ../0000:02:10.1
