This will help me to amend next revision appropriately. I have tried to describe what this flag is trying to represent. This is part of EHT MU-MIMO capabilities and driver may want to look at this flag for MU-MIMO configurations. Also this follows other parameters added to struct earlier. example: https://patchwork.kernel.org/project/linux-wireless/patch/1665006886-23874-2-git-send-email-quic_msinada@quicinc.com/
