2019-11-20mt76: move mt76_get_antenna in mt76_core moduleLorenzo Bianconi
Move mt76_get_antenna in mac80211.c in order to be reused by all drivers. Initialize .get_antenna function pointer for mt76x0, mt7603, mt7615 and mt76x2u drivers Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: move interface_modes definition in mt76_core moduleLorenzo Bianconi

2019-11-20mt76: refactor cc_lock locking schemeLorenzo Bianconi
Read busy counters not holding cc_lock spinlock since usb read can't be performed in interrupt context. Move cc_active and cc_rx counters out of cc_lock since they are not modified in interrupt context. Grab cc_lock updating cur_cc_bss_rx in mt76_airtime_report and do not hold rx_lock in mt76_update_survey. Moreover grab mt76 mutex in mt76_get_survey before running mt76_update_survey.

2018-11-30mt76: avoid queue/status spinlocks while passing tx status to mac80211Felix Fietkau
There is some code in the mac80211 tx status processing code that could potentially call back into the tx codepath. To avoid deadlocks, make sure that no tx related spinlocks are taken during the ieee80211_tx_status call. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-11-30mt76: add support for reporting tx status with skbFelix Fietkau
MT76x2/MT76x0 has somewhat unreliable tx status reporting, and for that reason the driver currently does not report per-skb tx ack status at all. This breaks things like client idle polling, which relies on the tx ack status of a transmitted nullfunc frame. This patch adds code to report skb-attached tx status if requested by mac80211 or the rate control module. Since tx status is polled from a simple FIFO register, the code needs to account for the possibility of tx status events getting lost. The code keeps a list of skbs for which tx status is required and passes them to mac80211 once tx status has been filled in and the DMA queue is done with it. If a tx status event is not received after one second, the status rates are cleared, and a succesful ACK is indicated to avoid spurious disassoc during assoc or client polling.

2018-11-06mt76: fix building without CONFIG_LEDS_CLASSArnd Bergmann
When CONFIG_LEDS_CLASS is disabled, or it is a loadable module while mt76 is built-in, we run into a link error: drivers/net/wireless/mediatek/mt76/mac80211.o: In function `mt76_register_device': mac80211.c:(.text+0xb78): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `devm_of_led_classdev_register' We don't really need a hard dependency here as the driver can presumably work just fine without LEDs, so this follows the iwlwifi example and adds a separate Kconfig option for the LED support, this will be available whenever it will link, and otherwise the respective code gets left out from the driver object.

2018-09-04mt76: Enable NL80211_EXT_FEATURE_CQM_RSSI_LISTKristian Evensen
Enable the use of CQM_RSSI_LIST with mt76-devices. The change has been tested with the mt7602, mt7603 and mt7621 PCI wifi-cards. I passed a list of RSSI thresholds to the driver, and when disconnecting/connecting the antenna(s) I got an event each time the RSSI went above/below a threshold. While I have not been able to test the change with any of the mt76 USB-devices (no access to a device), the RX RSSI management code is shared between the two device types. Thus, CQM should also work with the mt76 USB-devices. Signed-off-by: Kristian Evensen <kristian.evensen@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
