2018-06-27mt76: improve gain adjustment in noisy environmentsFelix Fietkau1-10/+16
When switching between low gain (high RSSI) and high gain settings, it can take a few seconds to adjust to the current environment. This can lead to short periods of time with extreme packet loss. When switching from low_gain=1 to low_gain=2, start with the same gain adjustment value instead of the lowest to avoid spikes of huge numbers of false CCA events Also avoid resetting adjustment values on switching between low_gain values 0 and 1, since it affects only the upper limit of vga adjustment Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-04-24mt76: rework tx power handlingFelix Fietkau1-25/+42
There were a number of issues in the existing tx power handling code: 1. The EEPROM target power for chain 0 refers to the actual output power after the channel and bandwidth delta have been added to the initial channel gain. This means the delta values should not be added/subtracted for the rate power calculation 2. When power is reduced significantly, the initial channel gain underflows very quickly, while the per-rate power offsets are high. This miscalculation causes effective tx power to be increased when it should actually be lowered. Fix this by trying to adjust the channel gain to the lowest power from the rate table. In case of under- or overflow, compensate by adding an appropriate delta to the rate power values. This makes power configuration more accurate on a wider range of configurable values Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
