Live can be interpreted differently i.e if it means just IFF_UP/powered or if it means connected. POWERED is more accurate to what this feature does. - Reworked the logic to check if individual interfaces are busy rather than globally. Simply checking local->scanning/roc_list was a large hammer, and puts limitations in that aren't needed. Now roc_list is traversed and only returns -EBUSY if the actual interface has ROC work. Similarly the scanning sdata is checked and -EBUSY is returned if it matches the sdata for which the address is being changed. - Only P2P_CLIENT/STATION iftypes are allowed to do a powered address change. I personally see no reason this is needed for other iftypes but if we want others to be supported I'm fine adding more. - Check return of drv_add_interface James Prestwood (2): include: nl80211: Add POWERED_ADDR_CHANGE feature mac80211: Support POWERED_ADDR_CHANGE feature include/uapi/linux/nl80211.h | 9 +++++ net/mac80211/iface.c | 67 ++++++++++++++++++++++++++++++++++-- net/mac80211/main.c | 2 ++ 3 files changed, 76 insertions(+), 2 deletions(-)
