[PATCH 3/4] staging: ks7010: add initial cfg80211 implementation

Currently we are in the process of replacing the WEXT interface with
the cfg80211 API. WEXT code is currently within a sub directory and
not included in the module build.
The driver is designed with various layers of abstraction;
- The main layer contains the net_device_ops callbacks. Also included
in this layer is the rx/tx code.
- The SDIO layer contains code specific to the SDIO hardware.
- The cfg80211 layer contains the implementation of the cfg80211
configuration API.
- The HIF (Host InterFace) layer provides driver policy and interfaces
between the cfg80211 layer and the FIL.
- The FIL (Firmware Interface Layer) provides mechanism for
interfacing with the firmware.
The firmware interface is derived from the WEXT driver, if we
write code to interface with the firmware as a separate abstraction
layer then the cfg80211 code and the rest of the driver functionality
can be written cleanly from scratch.
The separate layers are restricted to calls as indicated by the
following diagram, A --> B indicates layer A calls functions in layer B.
----> main (tx/rx) <---> SDIO
|
| |
| |
v v
cfg80211 <---> HIF
|
|
v
FIL
Implementation status is outlined in README.rst. A todo list is
included in TODO.rst.
Add initial cfg80211 implementation.

+=============================
+Key Stream SDIO Device Driver
+=============================
+
+Current Status
+--------------
+
+- Firmware Interface Layer complete.
+- Host Interface Layer, partial skeleton implementation.
+- cfg80211 minimal implementation.
+- SDIO mostly implemented.
+
+See drivers/staging/ks7010/TODO.rst for TODO's.
+
+Notes
+-----
+
+Some enum mib_attribute identifiers have been renamed. This reduces
+the continuity between the WEXT driver and the cfg80211 driver. To
+combat this, new identifiers are prefixed with 'MIB_' (instead of
+'DOT11_' or 'LOCAL_').
+
+We need to add readiness checks to a lot of functions, check vif is ready (cfg80211),
+check sdio function is enabled (sdio), check ks7010 device state (all).
+
+Description
+-----------
+
+Driver conversion from WEXT interface to cfg80211 API.
+
+The original KeyStream SDIO wireless driver brought into staging
+implements the WEXT interface.
+
+The WEXT driver is based on source code from the Ben Nanonote extra repository [1]
+which is based on the original v007 release from Renesas [2].
+
+[1] http://projects.qi-hardware.com/index.php/p/openwrt-packages/source/tree/master/ks7010/src
+[2] http://downloads.qi-hardware.com/software/ks7010_sdio_v007.tar.bz2
+
+Extensive refactoring has been done to the WEXT driver whilst in staging
+and the current mainline tip is untested.
+
+WEXT driver files :-
+ - ks7010_sdio.[ch] - SDIO code.
+ - ks_hostif.[ch] - Device interface.
+ - ks_wlan_net.c - WEXT interface.
+ - mic.[ch] - Custom Michael MIC implementation.
+ - eap_packet.h - EAP headers.
+ - ks_wlan_ioctl.h - WEXT IOCTL.
+
+cfg80211 driver files :-
+ - main.c - Main driver file (net_device_ops etc).
+ - ks7010.h - Main driver header file.
+ - common.h - Constant definitions and forward declarations.
+ - eap.h - EAPOL structure descriptions.
+ - sdio.[ch] - SDIO code.
+ - fil.[ch] - Firmware Interface Layer.
+ - fil_types.h - Internal FIL types.
+ - hif.[ch] - Host Interface Layer.
+ - cfg80211.c - cfg80211 API implementation.
+ - tx.c - Transmit path functions.
+ - rx.c - Recive path functions.
+
+cfg80211 driver files to do :-
+ - mic.[ch] - Interface to the kernel Michael MIC implementation.
+
+WEXT driver code now resides in the sub directory drivers/staging/ks7010/wext
+while the cfg80211 driver has the 'root' directory (drivers/staging/ks7010).
