IIRC that was addressed in my patches for fs-enet. what's happening: The PAL subsystem tries hard to be wise, an dif there are no link located, it starts to try forced mode, setting various stuff as link params and looking if link appeared or not. To keep consistency, I used the special flag passed via platform info, to just trust what ANEG had find out. Prolly we need to limit the forced aneg as well somehow - say give up after it failed to get link going at 10/HALF or smth like that. -- Sincerely, Vitaly
