+Subject: [PATCH] nl80211: Report disassociated STA / lost peer for the correct
+ BSS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We shouldn't use drv->ctx as it always points to the first BSS. When
+using FullMAC driver with multi-BSS support it resulted in incorrect
+treating nl80211 events. I noticed with with brcmfmac and BCM43602.
+
+Before my change I was getting "disassociated" on a wrong interface:
+wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated
+wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN)
+wlan0: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated
+
+With this patch it works as expected:
+wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated
+wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN)
+wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated
+
+This doesn't apply to hostapd dealing with SoftMAC drivers when handling
+AP SME & MLME is done it hostapd not the firmware.
