despite the fact that most people want to set exactly the same settings regardless of which card they have. It has been repeatidly suggested that this configuration should be done via ifconfig. This patch implements the required functionality in ifconfig and add support to the wi and an drivers. It also provides partial, untested support for the awi driver.
