Subject: [PATCH v2] staging: wlan-ng: Remove broken driver prism2_usb
Date: Tue, 26 Mar 2024 09:47:42 +0100 [thread overview]
Message-ID: <20240326084742.GA16228@matrix-ESPRIMO-P710> (raw)
Driver has a throughput of 200 to 800kByte/s in non encrypted
transmission. All encrypted modes are not working. WLAN without WPA2 is
useless these days. Driver is unused since April 2021 as a bug broke the
function. Find fix for bug in link below. Remove driver because of its
low performance and unusability.

v2: rebase and improved description
Checked for artifacts of wlan-ng and prism2_usb in MAINTAINERS.
Removed artifacts in Makefile.
Used the following hardware for tests: D-Link DWL-122 and Sinus 111
Tested with build and make clean to ensure that all is OK.

-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.

- * Portions of the development of this software were funded by
- * Intersil Corporation as part of PRISM(R) chipset product development.
- *
- * --------------------------------------------------------------------
- *
- * This file implements functions that correspond to the prism2/hfa384x
- * 802.11 MAC hardware and firmware host interface.
- *
- * The functions can be considered to represent several levels of
- * abstraction. The lowest level functions are simply C-callable wrappers
- * around the register accesses. The next higher level represents C-callable
- * prism2 API functions that match the Intersil documentation as closely
- * as is reasonable. The next higher layer implements common sequences
- * of invocations of the API layer (e.g. write to bap, followed by cmd).
- *
- * Common sequences:
- * hfa384x_drvr_xxx Highest level abstractions provided by the
- * hfa384x code. They are driver defined wrappers
- * for common sequences. These functions generally
- * use the services of the lower levels.
- *
- * hfa384x_drvr_xxxconfig An example of the drvr level abstraction. These
- * functions are wrappers for the RID get/set
- * sequence. They call copy_[to|from]_bap() and
- * cmd_access(). These functions operate on the
- * RIDs and buffers without validation. The caller
- * is responsible for that.
- *
- * API wrapper functions:
- * hfa384x_cmd_xxx functions that provide access to the f/w commands.
- * The function arguments correspond to each command
- * argument, even command arguments that get packed
- * into single registers. These functions _just_
- * issue the command by setting the cmd/parm regs
- * & reading the status/resp regs. Additional
- * activities required to fully use a command
- * (read/write from/to bap, get/set int status etc.)
- * are implemented separately. Think of these as
- * C-callable prism2 commands.
- *
- * Lowest Layer Functions:
- * hfa384x_docmd_xxx These functions implement the sequence required
- * to issue any prism2 command. Primarily used by the
- * hfa384x_cmd_xxx functions.
- *
- * hfa384x_bap_xxx BAP read/write access functions.
- * Note: we usually use BAP0 for non-interrupt context
- * and BAP1 for interrupt context.
- *
- * hfa384x_dl_xxx download related functions.
- *
- * Driver State Issues:
- * Note that there are two pairs of functions that manage the
- * 'initialized' and 'running' states of the hw/MAC combo. The four
- * functions are create(), destroy(), start(), and stop(). create()
- * sets up the data structures required to support the hfa384x_*
- * functions and destroy() cleans them up. The start() function gets
- * the actual hardware running and enables the interrupts. The stop()
- * function shuts the hardware down. The sequence should be:
- * create()
- * start()
- * .
- * . Do interesting things w/ the hardware
- * .
- * stop()
- * destroy()
- *
- * Note that destroy() can be called without calling stop() first.

- *
- * 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.
