Subject: [PATCH v2 4/4] wifi: ath11k: add AP power save support
Date: Mon, 20 Mar 2023 22:13:34 +0530 [thread overview]
Message-ID: <20230320164334.3325886-5-quic_mkenna@quicinc.com> (raw)
In-Reply-To: <20230320164334.3325886-1-quic_mkenna@quicinc.com>
From: Venkateswara Naralasetty <quic_vnaralas@quicinc.com>
AP goes into the power save mode if no stations
are connected and it will come out of power save
as and when any of the station associate to it.
Driver will advertise this flag SUPPORTS_AP_PS to
enable the AP power save in mac80211.
This AP power save capability can be used to save
power with the drawback of reduced range or delayed
discovery of the AP.
This feature is enabled in QCN9074, IPQ8074, IPQ5018, QCN6122.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
