This is the bcm57xx package. I have tested default vlan functions, but I dont have the equipment to test more advanced setups. The default vlan setup seems to be working fine. I also added the activate_gpio parameter which will make the driver activate the switch via gpio before probing for it. I'm not sure which method is best for autoload. For the wrt350n, I need the activate_gpio parameter. But its probably not a good idea to add that to the autoload file. On a system without a bcm57xx switch, isn't it a bad idea to mess with the gpios looking for the switch? Ideally, wouldn't it be best to load the bcm57xx module from broadcom-diag, after it has determined which router its on? I tried using 'request_module' from there, but had no success. For now, I am relying on preinit to load the bcm57xx module with activate_gpio param, after it has failed to load switch_robo and switch_adm.
