Subject: [PATCH v4 1/5] wifi: ath11k: add support to select 6 GHz Regulatory type
Date: Wed, 7 Jun 2023 05:48:06 -0400	[thread overview]
Message-ID: <20230607094810.26707-2-quic_wgong@quicinc.com> (raw)
In-Reply-To: <20230607094810.26707-1-quic_wgong@quicinc.com>

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.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
