* Note as well that /proc/net/wireless implementation has now moved in :

* Wireless Events (2002 -> onward) :
* --------------------------------
* Events are defined at the end of this file, and implemented in :
- * # include/linux/wireless.c
+ * # net/core/wireless.c
*
* Other comments :
* --------------
* (there is some stuff that will be added in the future...)
* I just plan to increment with each new version.

/*
* Changes :
* - Remove IW_MAX_GET_SPY because conflict with enhanced spy support
* - Add SIOCSIWTHRSPY/SIOCGIWTHRSPY and "struct iw_thrspy"
* - Add IW_ENCODE_TEMP and iw_range->encoding_login_index
+ *
+ * V16 to V17
+ * ----------
+ * - Add flags to frequency -> auto/fixed
+ * - Document (struct iw_quality *)->updated, add new flags (INVALID)
+ * - Wireless Event capability in struct iw_range
+ * - Add support for relative TxPower (yick !)

/* -------------------- DEV PRIVATE IOCTL LIST -------------------- */
-/* These 16 ioctl are wireless device private.
+/* These 32 ioctl are wireless device private, for 16 commands.
* Each driver is free to use them for whatever purpose it chooses,
* however the driver *must* export the description of those ioctls
* with SIOCGIWPRIV and *must* use arguments as defined below.
* We now have 32 commands, so a bit more space ;-).
* Also, all 'odd' commands are only usable by root and don't return the
* content of ifr/iwr to user (but you are not obliged to use the set/get
- * convention, just use every other two command).
- * And I repeat : you are not obliged to use them with iwspy, but you
+ * convention, just use every other two command). More details in iwpriv.c.
+ * And I repeat : you are not forced to use them with iwpriv, but you
* must be compliant with it.
