For WoWLAN support, it expect to support wake up based on discovery of one or more known SSIDs. This is the WIPHY_WOWLAN_NET_DETECT feature, which shows up as an NL80211 feature flag. With an upgrade iw, this shows up in 'iw phy' as: WoWLAN support: * wake up on network detection, up to 16 match sets And it can use command: "iw phy0 wowlan enable net-detect interval 5000 delay 30 freqs 2412 matches ssid foo" to configure the parameters of net detect. Firmware will do scan by the configured parameters after suspend and wakeup if it found matched SSIDs. Tested with QCA6174 hw3.0 with firmware WLAN.RM.4.4.1-00110-QCARMSWPZ-1.
