2018-11-30mt76: remove mcu_msg_allocStanislaw Gruszka
We almost always use patter like this: skb = mt76_mcu_msg_alloc(dev, &msg, sizeof(msg)); return mt76_mcu_send_msg(dev, skb, CMD_FUN_SET_OP, wait_resp); This is not needed, we can allocate skb in mcu_send_msg routine.

2018-11-30mt76x0: use band parameter for LC calibrationStanislaw Gruszka
We use always 1 as band parameter for MCU_CAL_LC, this break 2GHz, we should use 0 for this band instead. Patch fixes problems happened sometimes when try to associate with 2GHz AP and manifest by errors like below: [14680.920823] wlan0: authenticate with 18:31:bf:c0:51:b0 [14681.109506] wlan0: send auth to 18:31:bf:c0:51:b0 (try 1/3) [14681.310454] wlan0: send auth to 18:31:bf:c0:51:b0 (try 2/3) [14681.518469] wlan0: send auth to 18:31:bf:c0:51:b0 (try 3/3) [14681.726499] wlan0: authentication with 18:31:bf:c0:51:b0 timed out Fixes: 9aec146d0f6b ("mt76x0: pci: introduce mt76x0_phy_calirate routine") Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2018-11-30mt76x0: do not overwrite other MT_BBP(AGC, 8) fieldsStanislaw Gruszka
MT_BBP(AGC, 8) register has values depend on band in mt76x0_bbp_switch_tab, so we should not overwrite other fields than MT_BBP_AGC_GAIN when setting gain. This can fix performance issues when connecting to 2.4GHz AP.

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.

2018-11-30mt76: mt76x02: only override control->sta on sw-encrypted txFelix Fietkau
control->sta is set to NULL early when encryption is turned on for the station and info->control.hw_key is not set. This code is missing a check for the 802.11 header protected flag, otherwise it resets the station for other frames, e.g. client probing frames. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-11-30mt76: mt76x02: skip station tx status for non-sta wcid entriesFelix Fietkau
