+Subject: [PATCH 9/9] wifi: ath11k: Send PME message during wakeup from D3cold
+
+We are seeing system stuck on some specific platforms due to
+WLAN chip fails to wakeup from D3cold state.
+
+With this flag, firmware will send PME message during wakeup
+and this issue is gone.
+
+Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
