Currently, only the EHT IE in management frames is updated with
respect to MU-MIMO configurations, but this change is not
reflected in the hardware. Add support to propagate MU-MIMO
configurations to the hardware as well for AP mode. Similar
support for STA mode will be added in future.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
