Karthikeyan Periyasamy 8cd9357381 Revert "ath10k: send (re)assoc peer command when NSS changed" ... commit 55cc11da69 upstream. This reverts commit 55884c045d. 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. Firmware Assert log: ath10k_pci 0002:01:00.0: firmware crashed!
