Function Documentation

void rt2x00link_register

(

struct rt2x00_dev *

rt2x00dev

)

rt2x00link_register - Initialize link tuning & watchdog functionality : Pointer to &struct rt2x00_dev.

Initialize work structure and all link tuning and watchdog related parameters. This will not start the periodic work itself.

void rt2x00link_reset_tuner	(	struct rt2x00_dev *	rt2x00dev,
		bool	antenna
	)

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.

void rt2x00link_start_agc

(

struct rt2x00_dev *

rt2x00dev

)

rt2x00link_start_agc - Start periodic gain calibration : Pointer to &struct rt2x00_dev.

Definition at line 439 of file rt2x00link.c.

void rt2x00link_start_tuner

(

struct rt2x00_dev *

rt2x00dev

)

rt2x00link_start_tuner - Start periodic link tuner work : Pointer to &struct rt2x00_dev.

This start the link tuner periodic work, this work will be executed periodically until &rt2x00link_stop_tuner has been called.

While scanning, link tuning is disabled. By default the most sensitive settings will be used to make sure that all beacons and probe responses will be received during the scan.
