int iwlagn_rate_control_register

(

void

)

iwl_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 iwl_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 3361 of file rs.c.

void iwlagn_rate_control_unregister

(

void

)

iwl_rate_control_unregister - Unregister the rate control callbacks

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