From: Rafał Miłecki <rafal@xxxxxxxxxx> Modify wpa_driver_nl80211_set_operstate() to use BSS's ifindex instead of the main one. This results in calling RTM_SETLINK for interface that is actually used for a given BSS. It helps kernel to maintain proper "operstate" values. I noticed this "operstate" issue when working with wireless driver that doesn't happen to call netif helpers (like netif_carrier_on()). In such cases kernel doesn't update "operstate" properly on its own and hostapd can be helpful there.
A kindly reminder about this small PATCH. Could someone review / accept it, please?
