* This file declares the constants and types used in the interface
* between a wlan driver and the user mode utilities.
*
* Notes:
*  - Constant values are always in HOST byte order.  To assign
*    values to multi-byte fields they _must_ be converted to
*    ieee byte order.  To retrieve multi-byte values from incoming
*    frames, they must be converted to host order.
*
*  - The len member of the frame structure does NOT!!! include
*    the MAC CRC.  Therefore, the len field on rx'd frames should
*    have 4 subtracted from it.
*
* All functions declared here are implemented in p80211.c
*
* The types, macros, and functions defined here are primarily
* used for encoding and decoding management frames.  They are
* designed to follow these patterns of use:
*
* DECODE:
* 1) a frame of length len is received into buffer b
* 2) using the hdr structure and macros, we determine the type
* 3) an appropriate mgmt frame structure, mf, is allocated and zeroed
* 4) mf.hdr = b
*    mf.buf = b
*    mf.len = len
* 5) call mgmt_decode( mf )
* 6) the frame field pointers in mf are now set.  Note that any
*    multi-byte frame field values accessed using the frame field
*    pointers are in ieee byte order and will have to be converted
*    to host order.
*
* ENCODE:
* 1) Library client allocates buffer space for maximum length
*    frame of the desired type
* 2) Library client allocates a mgmt frame structure, called mf,
*    of the desired type
* 3) Set the following:
*    mf.type = <desired type>
*    mf.buf = <allocated buffer address>
* 4) call mgmt_encode( mf )
* 5) all of the fixed field pointers and fixed length information element
*    pointers in mf are now set to their respective locations in the
*    allocated space (fortunately, all variable length information elements
*    fall at the end of their respective frames).
* 5a) The length field is set to include the last of the fixed and fixed
*     length fields.  It may have to be updated for optional or variable
*	length information elements.
* 6) Optional and variable length information elements are special cases
*    and must be handled individually by the client code.
