This is the wlan-ng prism 2.5/3 USB driver for a wide range of
old USB wireless devices.
To compile this driver as a module, choose M here: the module
will be called prism2_usb.

TODO:
- checkpatch.pl cleanups
- sparse warnings
- move to use the in-kernel wireless stack
Please send any patches or complaints about this driver to Greg
Kroah-Hartman <greg@kroah.com> and don't bother the upstream wireless
kernel developers about it, they want nothing to do with it.

To-do list:
* Correct the coding style according to Linux guidelines; please read the document
at https://www.kernel.org/doc/html/latest/process/coding-style.html.
* Remove unnecessary debugging/printing macros; for those that are still needed
use the proper kernel API (pr_debug(), dev_dbg(), netdev_dbg()).
* Remove dead code such as unusued functions, variables, fields, etc..
* Use in-kernel API and remove unnecessary wrappers where possible.
* Fix bugs due to code that sleeps in atomic context.
* Remove the HAL layer and migrate its functionality into the relevant parts of
the driver.
* Switch to use LIB80211.
* Switch to use MAC80211.
* Switch to use CFG80211.
* Improve the error handling of various functions, particularly those that use
existing kernel APIs.

*
* 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.
