*  History:
*
*  28.02.04  mifi   First Version
*                   This file is a mix of several FreeBSD header files.
*                   I have put all the files together, because it was
*                   difficult to use the original files. I have try this
*                   but I must comment out to much to get it to work.
*                   The other "define" file is wlandef.h,
*                   here you will the rest of it.
*  03.03.04  mifi   Move debug switch to wlancfg.h
