From: linhuang <linhu...@ruijie.com.cn> Userspace tunnel doesn't have a valid device in the kernel. So get_ifindex() function (ioctl) always get error during adding a port, deleting a port or updating a port status.
The info log is "2021-08-29T09:17:39.830Z|00059|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on vxlan_sys_4789 device failed: No such device" If there are a lot of userspace tunnel ports on a bridge, the iface_refresh_netdev_status() function will spend a lot of time. So ignore userspace tunnel port ioctl(SIOCGIFINDEX) operation, just return ifindex=0.
