The updated MU-EDCA parameters from driver are part of an AP mode feature where firmware determines better MU-EDCA parameters based on channel conditions. The updated parameters are used and reported to user space to reflect in AP management frames. These dynamic parameter updates are offloaded to firmware for better user experience, thus details on algorithm are not provided. This is a driver specific feature, thus no spec references.
