Doh! Yes. Let me rephrase. When we detect link down, we put the ethernet HW block in reset, and repeat initialization when the link comes back up. Hmmm, however, at the moment, I only reset on an administrative (user-requested) link down, i.e. through ndo_stop. I would probably have to handle cable unplug/replug events as well. Or just consider the quirk to make flow control too complicated to implement correctly... Regards.
