For HTT there was ~1000-1400 msdu queue depth. After reaching that limit the driver would request mac80211 to stop queues. There was little control over what packets got in there as far as DA/RA was considered so it was rather easy to starve per-station traffic flows. With MU-MIMO this became a significant problem because the queue depth was insufficient to buffer frames from multiple clients (which could have different signal quality and capabilities) in an efficient fashion. Hence the new tx path in 10.4 was introduced: a pull-push mode. Firmware and host can share tx queue state via DMA. The state is logically a 2 dimensional array addressed via peer_id+tid pair. Each entry is a counter (either number of bytes or packets. Host keeps it updated and firmware uses it for scheduling Tx pull requests to host. This allows MU-MIMO to become a lot more effective with 10+ clients.
