[PATCH 03/15] ath11k: add support to select 6 GHz Regulatory type
Wen Gong
quic_wgong at quicinc.com
Tue Oct 26 04:19:01 PDT 2021
There are 3 types of regulatory rules for AP mode and 6 type for
station mode. Add wmi_vdev_type and ieee80211_ap_reg_power to
select the exact reg rules.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
