Poul-Henning Kamp 419d8080a4 Currently, each wireless networking driver has it's own control program
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.
