Tests on wlan-ng hardware have shown that this driver is broken since April 2021. Remove broken driver. Find fix for bug in link. Link: https://lore.kernel.org/linux-staging/5fa18cb8-3c51-4ac6-811e-63ae74f82f17@xxxxxxxxx/ Signed-off-by: Philipp Hortmann <philipp.g.hortmann@xxxxxxxxx> --- 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. With above fix inserted, non encrypted transmission is working. Throughput is 200 to 800kByte/s. WEP would need further investigation. --- drivers/staging/Kconfig | 2 - drivers/staging/Makefile | 1 - drivers/staging/wlan-ng/Kconfig | 13 - drivers/staging/wlan-ng/Makefile | 8 - drivers/staging/wlan-ng/README | 8 -

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. - * -------------------------------------------------------------------- - */ - -#include <linux/module.h> -#include <linux/kernel.h> -#include <linux/sched.h> -#include <linux/types.h> -#include <linux/slab.h> -#include <linux/wireless.h> -#include <linux/netdevice.h> -#include <linux/timer.h> -#include <linux/io.h> -#include <linux/delay.h> -#include <asm/byteorder.h> -#include <linux/bitops.h> -#include <linux/list.h> -#include <linux/usb.h> -#include <linux/byteorder/generic.h> - -#include "p80211types.h" -#include "p80211hdr.h" -#include "p80211mgmt.h" -#include "p80211conv.h" -#include "p80211msg.h" -#include "p80211netdev.h" -#include "p80211req.h" -#include "p80211metadef.h" -#include "p80211metastruct.h" -#include "hfa384x.h" -#include "prism2mgmt.h" - -enum cmd_mode { - DOWAIT = 0, - DOASYNC -};
