/*
* Changes :
* - Wireless Event capability in struct iw_range
* - Add support for relative TxPower (yick !)
*
- * V17 to V18 (From Jouni Malinen <jkmaline@cc.hut.fi>)
+ * V17 to V18 (From Jouni Malinen <j@w1.fi>)
* ----------
* - Add support for WPA/WPA2
* - Add extended encoding configuration (SIOCSIWENCODEEXT and
* related parameters (extensible up to 4096 parameter values)
* - Add wireless events: IWEVGENIE, IWEVMICHAELMICFAILURE,
* IWEVASSOCREQIE, IWEVASSOCRESPIE, IWEVPMKIDCAND
+ *
+ * V18 to V19
+ * ----------
+ * - Remove (struct iw_point *)->pointer from events and streams
+ * - Remove header includes to help user space
+ * - Increase IW_ENCODING_TOKEN_MAX from 32 to 64
+ * - Add IW_QUAL_ALL_UPDATED and IW_QUAL_ALL_INVALID macros
+ * - Add explicit flag to tell stats are in dBm : IW_QUAL_DBM
+ * - Add IW_IOCTL_IDX() and IW_EVENT_IDX() macros
+ *
+ * V19 to V20
+ * ----------
+ * - RtNetlink requests support (SET/GET)
+ *
+ * V20 to V21
+ * ----------
+ * - Remove (struct net_device *)->get_wireless_stats()
+ * - Change length in ESSID and NICK to strlen() instead of strlen()+1
+ * - Add IW_RETRY_SHORT/IW_RETRY_LONG retry modifiers
+ * - Power/Retry relative values no longer * 100000
+ * - Add explicit flag to tell stats are in 802.11k RCPI : IW_QUAL_RCPI
+ *
+ * V21 to V22
+ * ----------
+ * - Prevent leaking of kernel space in stream on 64 bits.
