+Subject: Revert "ath10k: send (re)assoc peer command when NSS changed"
+
+From: Karthikeyan Periyasamy <periyasa@codeaurora.org>
+
+commit 55cc11da69895a680940c1733caabc37be685f5e upstream.
+
+This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159.
+
+When Ath10k is in AP mode and an unassociated STA sends a VHT action frame
+(Operating Mode Notification for the NSS change) periodically to AP this causes
+ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during
+NSS update. Over the time (with a certain client it can happen within 15 mins
+when there are over 500 of these VHT action frames) continuous calls of
+WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust.
+
+To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS
+updates and no need to call ath10k_station_assoc(). So revert the original
+commit from 2014 as it's unclear why the change was really needed.
+Now the firmware assert doesn't happen anymore.
+
+Issue observed in QCA9984 platform with firmware version:10.4-3.5.3-00053.
+This Change tested in QCA9984 with firmware version: 10.4-3.5.3-00053 and
+QCA988x platform with firmware version: 10.2.4-1.0-00036.
