MAX_LEN_CFG_MAX_PSDU specify maximum transmitted by HW AMPDU length (0 - 8kB, 1 - 16kB, 2 - 32kB, 3 - 64kB). Set this option according to remote stations capabilities (based on HT ampdu_factor). However limit the value based our hardware TX capabilities as some chips can not send more than 16kB (factor 1). Limit for all chips is currently 32kB (factor 2), but perhaps for some chips this could be increased to 64kB by setting drv_data->max_psdu to 3. Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes (AP, IBSS, mesh) we limit according to less capable remote STA. We can not set bigger value to speed up communication with some stations and do not break communication with slow stations.
