- * mac80211 will filter frames based on authorization state in any case,

*
* @get_stats: return low-level statistics
*
- * @set_privacy_invoked: For devices that generate their own beacons and probe
- * response or association responses this updates the state of privacy_invoked
- * returns 0 for success or an error number.
- *
- * @get_sequence_counter: For devices that have internal sequence counters this

- * This callback seems not well-defined, tell us if you need it.

*
* @set_rts_threshold: Configuration of RTS threshold (if device needs it)

*
- * @erp_ie_changed: Handle ERP IE change notifications. Must be atomic.
- *
* @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max),
