iwlwifi: Tune radio to prevent unexpected behavior
We have seen the throughput dropped due to external noisy environment and the radio is out of tune. There are lot of plcp errors indicating this condition. Eventually the station can get de-authenticated by the Access Point. By resetting and tuning the radio, the plcp errors are reduced or eliminated and the throughput starts to rise. To prevent unexpected behavior such as drop in throughput or deauthentication, - The change provides the driver feature to monitor and tune the radio base on the statistics notification from the uCode. - It also allows the setting of the plcp error rate threshold via the plcp_delta under debugfs interface.
