   [PATCH] Wireless Extension dropped patchlet
   
   	This tiny bit of the last WE-17 patch was lost between me and
   you. I initially decided to wait to resubmit, but Chris Wedgwood
   reported that the MadWifi driver needs it. Sorry for not having pushed
   harder.
   	I recreated this patch, and tested with 2.6.10-rc1, and Chris
   tested it with MadWifi. Would you mind pushing that up to Linus ?
   
   Changelog :
   	o remove unneeded const
   	o spelling + comments
