Date: Fri, 24 Aug 2018 06:38:43 -0400 From: rpjday@...shcourse.ca To: netdev@...r.kernel.org Subject: what exactly does "volatile" mean WRT net_device_flags? 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
