Hi,
I am using ovs(2.8.1)+dpdk(17.05.2), and notice that there are lots of ovs log
as below:
2017-10-23T21:55:13.382Z|00241|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on
vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.384Z|00242|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on
vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.387Z|00243|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on
vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.390Z|00244|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on
vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.393Z|00245|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on
vxlan_sys_4789 device failed: No such device
Simply debug shows below change, which finally calls
netdev_vport_get_ifindex()->linux_get_ifindex(). In my opnion, it does NOT
apply to OVS+DPDK mode.
TUNNEL_CLASS("vxlan", "vxlan_sys", netdev_vxlan_build_header,
netdev_tnl_push_udp_header,
netdev_vxlan_pop_header,
NETDEV_VPORT_GET_IFINDEX), àon
ovs2.7, it is NULL
Any idea for fix?
Br,
Wang Zhike
