wifi: rt2x00: introduce DMA busy check watchdog for rt2800 When I tried to fix the watchdog of rt2800, I found that sometimes the watchdog can not reset the hung device. This is because the queue is not completely stuck, it just becomes very slow. The MTK vendor driver for the new chip MT7603/MT7612 has a DMA busy watchdog to detect device hangs by checking DMA busy status. This watchdog implementation is something similar to it. To reduce unnecessary reset, we can check the INT_SOURCE_CSR register together as I found that when the radio hung, the RX/TX coherent interrupt will always stuck at triggered state. The 'watchdog' module parameter has been extended to control all watchdogs(0=disabled, 1=hang watchdog, 2=DMA watchdog, 3=both). This new watchdog function is a slight schedule and it won't affect the transmission speed. So we can turn on it by default. Due to the INT_SOURCE_CSR register is invalid on rt2800 USB NICs, the DMA busy watchdog will be automatically disabled for them. Tested on MT7620 and RT5350.

wifi: rt2x00: improve MT7620 register initialization 1. Do not hard reset the BBP. We can use soft reset instead. This change has some help to the calibration failure issue. 2. Enable falling back to legacy rate from the HT/RTS rate by setting the HT_FBK_TO_LEGACY register. 3. Implement MCS rate specific maximum PSDU size. It can improve the transmission quality under the low RSSI condition. 4. Set BBP_84 register value to 0x19. This is used for extension channel overlapping IOT.

rt2800: set MAX_PSDU len according to remote STAs capabilities 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.
