Subject: [PATCH 3/7] wifi: ath12k: add WoW net-detect functionality
Date: Fri, 10 May 2024 14:47:44 +0800

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.

Note that firmware crashes if we enable it for both
P2P vdev and station vdev simultaneously because
firmware can only support one vdev at a time. Since
there is rare scenario for a P2P vdev to do net-detect,
skip it for P2P vdevs.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
