But the firmware only reports the overall capabilities and not the one which are specific for mesh. Some of them (TWT, MU UL/DL, TB PPDU, ...) require an infrastructure setup with a main STA (AP) controlling the operations. This is not the case for mesh and thus these capabilities are removed from the list of capabilities.
