[PATCH 03/11] wifi: ath12k: process EHT capabilities from target
Aloka Dixit

Wed Mar 29 16:11:37 PDT 2023
Add WMI support to process the EHT capabilities passed by the
hardware. Add required EHT specific definitions in
structures ath12k_band_cap and ath12k_wmi_svc_rdy_ext_parse.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
