wifi: ath12k: support MLO for WCN7850
|
expand
|
WCN7850 firmware uses API-1 so it can not advertise MLO support via firmware IE, but instead it uses single_chip_mlo_support flag in QMI message, the first three patches serve for this purpose. Currently ml_arg->assoc_link flag is not set in WMI_VDEV_START_REQUEST_CMDID, this result in WCN7850 firmware crash in MLO case, so patch [04/9] sets it for assoc link. Patch [05/9] makes sure we do assoc for assoc link before any other links, as requested by WCN7850 firmware. Patch [08/9] change to send REO queue configuration to firmware for all links including non-primary link. For that purpose, preparation is done in patch [06,07/9]. The last patch increases number of different channels to 2 for single pdev device, to avoid failing in bringup the second link.
