snowball-init can't set wlan mac address

[Matthew Bentham]

Here:

http://www.igloocommunity.org/support/BSP_User_Guides#Change_the_MAC_adress

It says that mac address is a parameter to the cw1200_wlan module.

Here:

http://www.igloocommunity.org/support/Snowball-Init

It says that you can set the mac address in /etc/snowballrc via the "WLAN_MAC" variable, and indeed this makes it pass the argument to the cw1200_wlan module.

However, wlan mac address is actually a parameter to the cw1200_core module, as documented here:

http://www.igloocommunity.org/support/Running_WLAN

And setting it on the cw1200_wlan module just makes that module fail to load.

Matthew: Can you please provide more detailed information. We need to know the release you are using, the kernel (uname -r) and the commands used.

This is valid for the stable-3.3 tree at least:

http://www.igloocommunity.org/gitweb/?p=kernel/igloo-kernel.git;a=blob;f=drivers/staging/cw1200/main.c;hb=refs/heads/stable-linux-ux500-3.3#l49

but as the parameter is defined in main.c it will be built into cw1200_core, not cw1200_wlan:

http://www.igloocommunity.org/gitweb/?p=kernel/igloo-kernel.git;a=blob;f=drivers/staging/cw1200/Makefile;hb=refs/heads/stable-linux-ux500-3.3

So either the script needs changing or the module parameter location. It's not obvious to me why the mac address that affects the wifi interface is defined in the core module.
