-/************************** DOCUMENTATION **************************/
-/*
- * API definition :
- * --------------
- * See <linux/wireless.h> for details of the APIs and the rest.
- *
- * History :
- * -------
- *
- * v1 - 5.12.01 - Jean II
- * o Created this file.
- *
- * v2 - 13.12.01 - Jean II
- * o Move /proc/net/wireless stuff from net/core/dev.c to here
- * o Make Wireless Extension IOCTLs go through here
- * o Added iw_handler handling ;-)
- * o Added standard ioctl description
- * o Initial dumb commit strategy based on orinoco.c
- *
- * v3 - 19.12.01 - Jean II
- * o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
- * o Add event dispatcher function
- * o Add event description
- * o Propagate events as rtnetlink IFLA_WIRELESS option
- * o Generate event on selected SET requests
- *
- * v4 - 18.04.02 - Jean II
- * o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
- *
- * v5 - 21.06.02 - Jean II
- * o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
- * o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
- * o Add IWEVCUSTOM for driver specific event/scanning token
- * o Turn on WE_STRICT_WRITE by default + kernel warning
- * o Fix WE_STRICT_WRITE in ioctl_export_private() (32 => iw_num)
- * o Fix off-by-one in test (extra_size <= IFNAMSIZ)
- *
- * v6 - 9.01.03 - Jean II
- * o Add common spy support : iw_handler_set_spy(), wireless_spy_update()
- * o Add enhanced spy support : iw_handler_set_thrspy() and event.
- * o Add WIRELESS_EXT version display in /proc/net/wireless
- *
- * v6 - 18.06.04 - Jean II
- * o Change get_spydata() method for added safety
- * o Remove spy #ifdef, they are always on -> cleaner code
- * o Allow any size GET request if user specifies length > max
- * and if request has IW_DESCR_FLAG_NOMAX flag or is SIOCGIWPRIV
- * o Start migrating get_wireless_stats to struct iw_handler_def
- * o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
- * Based on patch from Pavel Roskin <proski@gnu.org> :
- * o Fix kernel data leak to user space in private handler handling
- *
- * v7 - 18.3.05 - Jean II
- * o Remove (struct iw_point *)->pointer from events and streams
- * o Remove spy_offset from struct iw_handler_def
- * o Start deprecating dev->get_wireless_stats, output a warning
- * o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
- * o Don't lose INVALID/DBM flags when clearing UPDATED flags (iwstats)
- *
- * v8 - 17.02.06 - Jean II
- * o RtNetlink requests support (SET/GET)
- *
- * v8b - 03.08.06 - Herbert Xu
- * o Fix Wireless Event locking issues.
- *
- * v9 - 14.3.06 - Jean II
- * o Change length in ESSID and NICK to strlen() instead of strlen()+1
- * o Make standard_ioctl_num and standard_event_num unsigned
- * o Remove (struct net_device *)->get_wireless_stats()
- *
- * v10 - 16.3.07 - Jean II
- * o Prevent leaking of kernel space in stream on 64 bits.
