The Yukon Optima supports a reverse auto-negotiation feature that was incorrectly setup, and not needed. The feature could be used to allow wake-on-lan at higher speeds. But doing it correctly would require other changes to initialization. Reported-by: Pavel Mateja Signed-off-by: Stephen Hemminger --- This version is for current driver organization (post 3.1).
