+*
+* 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.
