i'm still unclear what the qualifier "volatile" means when used WRT net_device_flags. the explanation given in include/uapi/linux/if.h:
"Flags which can be toggled through sysfs are annotated below, note that only a few flags can be toggled and some other flags are always preserved from the original net_device flags even if you try to set them via sysfs. Flags which are always preserved are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile are annotated below as such." as i read it, volatile simply means not modifibale from sysfs. is it that simple? rday
