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: + + --- Begin Message --- + + * From: TJ <tj@xxxxxxxxxxx> + * Date: Mon, 05 Feb 2007 19:28:59 +0000 + + 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. + + --------- + On Mon, 2007-02-05 at 13:54 -0500, Pathare, Viren M (Viren) wrote: + + + "I would like to confirm that the two drivers; Linux LKM Wireless Driver + Source Code, Version 7.18 and Linux LKM Wireless Driver Source Code, + Version 7.22 comply with Open Source BSD License.
