Staging: wlags49_h2: add Agere driver for HERMES II and HERMES II.5 chipsets

WLAN driver for cards using the HERMES II and HERMES II.5 chipset

Based on Agere Systems Linux LKM Wireless Driver Source Code,
Version 7.22; complies with Open Source BSD License.

The software is a modified version of wl_lkm_722_abg.tar.gz from the
Agere Systems website, addapted for Ubuntu 9.04 and modified to
fit in the current Linux kernel (2.6.31).

Modified for kernel 2.6 by Henk de Groot <pe1dnn@amsat.org>

+DESCRIPTION
+
+The software is a modified version of wl_lkm_722_abg.tar.gz from the
+Agere Systems website, addapted for Ubuntu 9.04.
+
+Modified for kernel 2.6 by Henk de Groot <pe1dnn@amsat.org>
+Based on 7.18 version by Andrey Borzenkov <arvidjaar@mail.ru> $Revision: 39 $
+
+INSTALLATION
+
+Unpack in a new directory.
+
+Open a terminal screen.
+
+Change directory to the source directory
+
+Type command
+
+make
+
+and wait until it is finshed. Now you have build the module
+wlags49_h2_cs; this module is meant for a HERMES II card.
+
+The driver is tested with a Thomson SpeedTouch 110 Wireless PC Card.
+For the test Station mode was used with WEP. The driver is supposed
+to support WAP and as accesspoint that is NOT tested.
+
+If you have a card using the HERMES II.5 chip you have to make
+changes to the Makefile and uncomment -DHERMES25. This will build
+driver wlags49_h25_cs.
+
+Note: You can detemine the type with command "pccardctrl info"
+        MANIFID: 0156,0002 = HERMES - not supported by this driver
+        MANIFID: 0156,0003 = HERMES II   (Wireless B)
+        MANIFID: 0156,0004 = HERMES II.5 (Wireless B/G)
+
+After succesfull compile type command
+
+sudo make install
+
+to install the module.
+
+Now the card should be recognized. It should be able to configure
+and use the card with NetworkManager. Wpa_supplicant also works, as does
+manual configuration using the iwconfig/iwlist programs.
+
+Note: I only tested Station mode with WEP but if I didn't break anything
+WPA and AP mode should also work; note however that WPA was experimental
+in the original Agere driver!
+
+Note: to compile as AP change the makefile and remove the line
+-DSTA_ONLY \
+
+(or comment it, but in that case make sure to move it after all the
+ flags you want to use)
+
+CHANGES
+
+The HCF functions to control the card are virtually unchanged, the only
+changes are meant to fix compiler warnings. The only real change is in
+HCF_WAIT_WHILE which now has a udelay(2) added to give a small delay.
+
+The linux driver files (wl_xxxx.c) are changed in the following ways:
+- Addaptations of Andrey Borzenkov applied to 7.22 source
+- Alterations to avoid most HCF_ASSERTs
+-- Switching interrupts off and on in the HCF
+-- Bugfixes, things that were aparently wrong like reporting link status
+   change which checked a variable that was not changed in HCF anymore.
+-- Used on WEP but setting keys via SIOCSIWENCODEEXT was not supported
+-- Recovery actions added
+
+The major problem was the order in which calls can be made. The original
+looks like a traditonal UNIX driver. To call an "ioctl" function you
+have to "open" the device first to get a handle and after "close" no
+"ioctl" function can be called anymore. With the 2.6 driver this all
+changed; the former ioctl functions are now called before "open" and
+after "close", which was not expected. One of the problems was enable/
+disable of interrupts in the HCF. Interrupt handling starts at "open"
+so if a former "ioctl" routinge is called before "open" or after "close"
+then nothing should be done with interrupt switching in the HCF. Once
+this was solved most HCF_ASSERTS went away.
+
+The last point, recovery actions added, needs some clarification.
+Starting the card works most of the time, but unfortunately not always.
+At a few times recovery code was added; when the card starts to
+misbehave or the communication between the HCF and the card is
+out of sync and the HCF enters DEFUNCT mode everything is reset and
+reinitialized. Note, hcf.c contains a lot of documentation. It takes
+some time but slowly some things become clear. Also some unresolved
+issues are mentioned in hcf.c, so there are still unknown bugs.
+
+The card problems are almost in all cases when starting up and before
+the first association with an AP, once the card is in operation it
+seems to stay that way; when debugging no HCF_ASSERTS appear anymore.
+Note: some HCF_ASSERTS still appear, in a number of cases it is a real
+error, for example at card removal the missing card is detected.
+
+LICENSE
+
+The Agere Systems license applies. This is why I include the original
+README.wlags49. The instructions in that file are bogus now. I also
+include the man page. Eventhough setting parameters on the module
+does not work anymore but it provides some information about all the
+settings.
+
+I have not have personal contact with Agere, but others have. Agere
+agreed to make their software available under the BSD licence.
+This driver is based on the 7.22 version.
+
+The following was mailed by Agere to Andrey Borzenkov about this:

+
+    Hi Andrey,
+
+    I've got some good news for you/us/the world of Hermes :)
+
+    I got a reply from the legal representative at Agere confirming that
+    their source-code is BSD licensed, and I've included the contents of the
+    email here.
+
+    I hope this re-assures you so that your excellent work on the drivers
+    can be made widely available for other hackers to work with.
+
+    Regards,
+
+    TJ.
