>From the question, I infer that you are referring to Ethernet device
drivers. In the FreeBSD model, devices fit into one or more of a set of
classes. Each class has an established, device-independant mechanism for
controlling driver parameters. In the case of Ethernet drivers,
parameters are controlled via the driver's ioctl interface.
You should be able to find good examples of this in the source for other
drivers similar to your own. If you have more specific questions, please
feel free to ask them here.
