2019-04-12mt76x02: avoid status_list.lock and sta->rate_ctrl_lock dependencyStanislaw Gruszka
Move ieee80211_tx_status_ext() outside of status_list lock section in order to avoid locking dependency and possible deadlock reposed by LOCKDEP in below warning.

2019-03-07mt76: mt76x02: reduce false positives in ED/CCA tx blockingFelix Fietkau
Full tx blocking (as opposed to CCA blocking) should only happen if there is a continuous non-802.11 signal above the energy detect threshold. Unfortunately the ED/CCA counter can't detect that, as it also counts 802.11 signals as busy. Similar to the vendor code, implement a learning mode that waits until the AGC gain has already been adjusted to the lowest value (due to false CCA events), and the number of false CCA events still remains high, and the blocking threshold is exceeded for more than 5 seconds.

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.
