Specifically, this update changes how the beacon frame with MBSS IE is delivered to the driver, in conjunction with this kernel change: https://patchwork.kernel.org/project/linux-wireless/patch/20250729084932.264155-1-mingyen.hsieh@mediatek.com/

In various tests, it was observed that there were frequent disconnections in cases where the host was closer in proximity to the AP, but that there were instances where a connection could be maintained if they were farther away.
