Re: [PATCH 1/1] drivers/net: param for lapbether for specific ethernetdevice

I will be using an Ubuntu 10.04 kernel with the 'eth_dev' module parameter patch. I appreciate a better solution needs to be designed but it is not one I can contribute to. I still advocate the patch as an improvement on the current non functional situation.

The lapbether driver binds to the first ethernet device that comes up.
This causes problems in hardware with multiple ethernet interfaces,
potentially resulting in the LAPB traffic on the wrong interface.
Have added a module parameter 'eth_dev' to specify the ethernet
interface over which lapbether should operate. The module behaves
as before if no device is specified.

Tested on 2.6.32-45-generic.

I rejected this patch last night, stating that module parameters are
deeply discouraged and therefore you need to create a runtime mechanism
to control this.
