The urtwn hardware transmits FF/A-MSDU just fine - it takes an 802.11 frame and will dutifully send the thing. So: * bump RX queue up from 1. Why's it 1? That's really silly. * Add the "software A-MSDU" encap capability bit. * bump the TX buffer size up so we can at least send A-MSDU frames. * track active frames submitted to the NIC - we can't make assumptions about how many are in flight in the NIC though. For 88E parts we could use per-packet TX indication, but for R92 parts we can't. So, just fake it somewhat. * Kick the transmit queue when we finish reception; try to avoid stalls. * Kick the FF queue a little more regularly. A-MSDU TX won't happen until the net80211 side is done, but atheros fast-frames support should now work. Tested: * urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R ; A-MSDU transmit. |
