Since commit 41977e86c984 ("rt2x00: add support for MT7620") we do not initialize TX_PIN_CFG setting. This cause breakage at least on some RT3573 devices.

2017-01-19rt2800: remove warning on bcn_num != rt2x00dev->intf_beaconingStanislaw Gruszka1-2/+0
Since rt2800pci update beacon settings asynchronously from tbtt tasklet, without beacon_skb_mutex protection, number of currently active beacons entries can be different than number pointed by rt2x00dev->intf_beaconing.

2017-01-17rt2800: tune TX_RTS_CFG configStanislaw Gruszka1-2/+2
Enable RTS frame retry fall-back and limit number of RTS retries to 7 what is default number of retries for small frames. As RTS/CTS is used for TXOP protection, those settings prevent posting lots of RTS frames when remote station do not response with CTS at the moment. After sending 7 RTS's the HW will start back-off mechanism and after it will start posing RTS again to get access to the medium.

2017-01-17rt2800: change default retry settingsStanislaw Gruszka1-2/+9
We do not have option to set per frame retry count. We have only global TX_RTY_CFG registers which specify the number or retries. Set setting of that register to value that correspond rate control algorithm number of frame post (number of retries + 1), which is 3 for aggregated frames. This should help with big amount of retries on bad conditions, hence mitigate buffer-bloat like problems.

2016-12-30rt2800: replace msleep() with usleep_range() on channel switchStanislaw Gruszka1-2/+4
msleep(1) can sleep much more time then requested 1ms, this is not good on channel switch, which we want to be performed fast (i.e. to make scan faster). Replace msleep() with usleep_range(), which has much smaller maximum sleeping time boundary. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-12-30rt2800: set MAX_PSDU len according to remote STAs capabilitiesStanislaw Gruszka1-3/+42
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.
