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>

This procedure can sleep, hence mdelay is not needed. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-12-30rt2800: warn if doing VCO recalibration for unknow RF chipStanislaw Gruszka1-0/+2
Since we reset TX_PIN_CFG register, we have to finish recalibration. Warn if this is not possible. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-12-30rt2800: rename adjust_freq_offset functionStanislaw Gruszka1-8/+8
We have different modes of adjusting freq offset on different chips. Call current adjustment similarly like vendor driver - mode1 . 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.

Sending frames in CCK rates on HT can cause performance problems. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-11-23rt2800: tune *_PROT_CFG parametersStanislaw Gruszka1-8/+8
Use RTS/CTS protection for TXOP on all rates modes as default and disable CCK rates (this cause performance problems). Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-11-23rt2800: use RTS/CTS protection instead of CTS-to-selfStanislaw Gruszka1-3/+3
Change default to RTS/CTS protection. This has a cost of transmitting one more control frame (RTS) however protect us from traffic from hidden node. On station mode will use CTS-to-self if AP will configure that for the network. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2016-11-23rt2800: correct AUTO_RSP_CFGStanislaw Gruszka1-4/+2
Initialize AUTO_RSP_CFG register to similar value as vendor driver does. Do not set BAC_ACK_POLICY based on short preamble setting, those are unrelated. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-11-23rt2800: do not overwrite WPDMA_GLO_CFG_WP_DMA_BURST_SIZEStanislaw Gruszka1-1/+0
We already initlized WPDMA_GLO_CFG_WP_DMA_BURST_SIZE to 3 on rt2800_init_registers() for USB devices. For PCI devices we will use HW default setting, which is 2, so patch does not change behaviour on PCI devices.

2016-11-23rt2800: correctly report MCS TX parametersStanislaw Gruszka1-10/+13
We should only set IEEE80211_HT_MCS_TX_RX_DIF when TX and RX MCS sets are not equal, i.e. when number of tx streams is different than number of RX streams. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-11-09rt2x00: add support for mac addr from device treeMathias Kresin1-4/+1
On some devices the EEPROMs of Ralink Wi-Fi chips have a default Ralink MAC address set (RT3062F: 00:0C:43:30:62:00, RT3060F: 00:0C:43:30:60:00). Using multiple of these devices in the same network can cause nasty issues. Allow to override the MAC in the EEPROM with (a known good) one set in the device tree to bypass the issue.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg1-15/+15
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2016-01-25rt2x00: fix monitor mode regressionEli Cooper1-1/+2
Since commit df1404650ccb ("mac80211: remove support for IFF_PROMISC") monitor mode for rt2x00 has been made effectively useless because the hardware filter is configured to drop packets whose intended recipient is not the device, regardless of the presence of monitor mode interfaces. This patch fixes this regression by adding explicit monitor mode support, and by configuring the hardware filter accordingly.

2016-01-14mac80211: pass block ack session timeout to to driverSara Sharon1-3/+4
Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.
