[PATCH 23/27] mac80211: remove unused ioctls (4)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The ioctls
 * PRISM2_HOSTAPD_GET_DOT11COUNTERSTABLE
 * PRISM2_HOSTAPD_GET_LOAD_STATS
 * PRISM2_HOSTAPD_GET_TX_STATS
 * PRISM2_HOSTAPD_SCAN_REQ
 * PRISM2_STA_GET_STATE
 * PRISM2_HOSTAPD_FLUSH_IFS

are not used by hostapd or wpa_supplicant.
