No.
As for link detection on the switch connected to this card:
If I have WoL turned off, then I don't get link beat detection.
If I have WoL turned on, then PHY won't be powered down, and I get
link detection on the switch.

I don't get link beat detection with the original driver either, when
interface is down
(unless I pass it -a, but then it will bring the interface up).
