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. +* -------------------------------------------------------------------- +*/ + +#ifndef _P80211MGMT_H +#define _P80211MGMT_H +
