The timer is only used when the interface is going up, going down, or
the speed is changed. All these things are not time critical (in my
opinion). So I believe the driver can be used as-is in a realtime
environment, or do these Linux functions prevent the driver from
running in primary mode?

I agree it would be nice if it would be fixed properly. However, it
might be a while before I get around to it.
