Subject: [PATCH] ath11k: set DTIM policy to stick mode for station interface
Git-commit: 55e18e5a76ab5de2286d4bac703a78066278f475
Patch-mainline: v5.17-rc1
References: bsc#1206451
Set DTIM policy to DTIM stick mode, so station follows AP DTIM
interval rather than listen interval which is set in peer assoc cmd.
DTIM stick mode is more preferred per firmware team request.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
