Hi This is v2 of the netdev naming-policy series. You can find v1 here: http://thread.gmane.org/gmane.linux.kernel/1657015 Changes in v2: - fix mac80211 core to set NET_NAME_ENUM for wlan%d kernel-provided names - acked-by udev developers This series implements a new sysfs attribute for netdevs called "name_assign_type". It provides an integer that describes where an interface name comes from. See Patch #1 for a description of this attribute. It is modelled after the existing "addr_assign_type" attribute. The main use-case is to allow udev to skip applying reliable ifnames to virtual devices. For instance, if wifi-P2P devices are created, wpas already provides a suitable naming-policy and udev shouldn't touch these devices. Same is true for other virtual devices. The idea is that if a device-name was provided by user-space, we should always prefer fixing this naming-policy instead of making udev rename the device. For kernel provided names that's hardly possible, though. Providing the naming-policy source via sysfs is thus a simple way to see whether renames are needed. Additionally, this field allows to detect whether a netdev has been manually renamed, which is quite useful for debugging and during crash-recovery. Furthermore, it fixes real udev bugs if a netdev is already renamed in the initrd and udev only runs in the real root. Detecting renames avoids overwriting custom user provided names.
