void rt2x00link_reset_tuner	(	struct rt2x00_dev *	rt2x00dev,

	)

rt2x00link_reset_tuner - Reset periodic link tuner work : Pointer to &struct rt2x00_dev. : Should the antenna tuning also be reset

The VGC limit configured in the hardware will be reset to 0 which forces the driver to rediscover the correct value for the current association. This is needed when configuration options have changed which could drastically change the SNR level or link quality (i.e. changing the antenna setting).

Resetting the link tuner will also cause the periodic work counter to be reset. Any driver which has a fixed limit on the number of rounds the link tuner is supposed to work will accept the tuner actions again if this limit was previously reached.

If is set to true a the software antenna diversity tuning will also be reset.
