From fec4b898f369a9b9d516f7bfc459eb4a8c5ceb2c Mon Sep 17 00:00:00 2001

Subject: [PATCH] ath11k: Add WoW net-detect functionality

Implement net-detect feature by setting flag
WIPHY_WOWLAN_NET_DETECT if firmware supports this
feature. Driver sets the related PNO configuration
to firmware before entering WoW and firmware then
scans periodically and wakes up host if a specific
SSID is found.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
