Function Documentation

int il4965_rate_control_register

(

void

)

il_rate_control_register - Register the rate control algorithm callbacks

Since the rate control algorithm is hardware specific, there is no need or reason to place it as a stand alone module. The driver can call il_rate_control_register in order to register the rate control callbacks with the mac80211 subsystem. This should be performed prior to calling ieee80211_register_hw

Definition at line 2827 of file 4965-rs.c.

void il4965_rate_control_unregister

(

void

)

il_rate_control_unregister - Unregister the rate control callbacks

This should be called after calling ieee80211_unregister_hw, but before the driver is unloaded.
