FROMLIST: wifi: ath12k: Set DTIM policy to stick mode for station interface - #974
Conversation
…erface Currently, the station always follows the listen interval regardless of the DTIM value. The DTIM function does not work as expected. The default value of the listen interval is 5 so that the STA wakes up every 500ms when power save is on. This can cause a data transmission delay. Set the DTIM policy to DTIM stick mode so that the station follows the AP DTIM interval rather than the listen interval, which is set in the peer assoc command. DTIM stick mode is preferable per the firmware team's request. Apply this only for STA vdevs and only when STA power save is supported, to avoid affecting unsupported targets and P2P client vdevs. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3 Link: https://lore.kernel.org/all/20260717014302.284034-1-daizhuang.bai@oss.qualcomm.com/ Signed-off-by: Daizhuang Bai <daizhuang.bai@oss.qualcomm.com>
