2019-03-19mt76x02: do not enable RTS/CTS by defaultStanislaw Gruszka1-1/+1
My commit 26a7b5473191 ("mt76x02: set protection according to ht operation element") enabled by default RTS/CTS protection for OFDM and CCK traffic, because MT_TX_RTS_CFG_THRESH is configured to non 0xffff by initvals and .set_rts_threshold callback is not called by mac80211 on initialization, only on user request or during ieee80211_reconfig() (suspend/resuem or restart_hw). Enabling RTS/CTS cause some problems when sending probe request frames by hcxdumptool penetration tool, but I expect it can cause other issues on different scenarios. Restore previous setting of RTS/CTS being disabled by default for OFDM/CCK by changing MT_TX_RTS_CFG_THRESH initvals to 0xffff.

2019-03-19mt76x02u: check chip version on probeStanislaw Gruszka1-3/+7
Since some USB device IDs are duplicated between mt76x0u, mt7601u and mt76x2u device, check chip version on probe and return error if not match the driver. Don't think this is serious issue, probe most likely will fail at some other point for wrong device, but we do not have to configure it if we know is not our device.

2019-02-26mt76usb: use synchronous msg for mcu command responsesStanislaw Gruszka1-11/+0
Use usb_bulk_msg for reading MCU command responses. This simplify code a lot. Together with 97a3005759c ("mt76usb: allow mt76u_bulk_msg be used for reads") it also fix possible problems with rx data buffers not being aligned and contained within single page. After doing page_frag_alloc(1024) consecutive page_frag_alloc(PAGE_SIZE) will alloc PAGE_SIZE buffer at PAGE_SIZE - 1024 offset.

2019-02-26mt76: mt76x02: fix ED/CCA enabling/disablingFelix Fietkau3-5/+5
ED/CCA needs to be disable before stopping the MAC to avoid hangs from tx being blocked. It must only be enabled again after the MAC has been started again. In many places this wasn't done properly, so fix this by always clearing the relevant ED/CCA bits in mt76x2_mac_stop and set it up again after channel change or calibration is done Signed-off-by: Felix Fietkau <nbd@nbd.name>

2018-11-30mt76x02: run calibration after scanningStanislaw Gruszka1-1/+1
If we are associated and scanning is performed, sw_scan_complete callback is done after we get back to operating channel, so we do not perform queue cal work. Fix this queue cal work from sw_scan_complete(). On mt76x0 we have to restore gain in MT_BBP(AGC, 8) register after scanning, as it was multiple times modified by channel switch code. So queue cal work without any delay to set AGC gain value. Similar like in mt76x2 init AGC gain only when set operating channel and just check before queuing cal work in sw_scan_complete() if initialization was already done.

Remove wait argument from mt76x02_mcu_function_select and wait for response when function is not Q_SELECT, what is the same behaviour like in vendor driver.
