* 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
* must be compliant with it.  */
