Subject: wifi: ath12k: parse and save sbs_lower_band_end_freq from WMI_SERVICE_READY_EXT2_EVEN... 
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=241d130f1419fd99923d99aff6e40490a4c34d93;p=linux-block.git

wifi: ath12k: parse and save sbs_lower_band_end_freq from WMI_SERVICE_READY_EXT2_EVENTID event

Firmware sends the boundary between lower and higher bands in
ath12k_wmi_dbs_or_sbs_cap_params structure embedded in
WMI_SERVICE_READY_EXT2_EVENTID event. The boundary is needed when
updating frequency range in the following patch. So parse and save
it for later use. Note ath12k_wmi_dbs_or_sbs_cap_params is placed
after some other structures, so placeholders for them are added
as well.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
