You're welcome. For what it's worth, the Linux driver uses the second set of
values referenced below. I think one of the two drivers likely has a bug, but
I'm not currently in a position to test it on hardware, so you don't need to fix
it on my account :)
Thanks and regards,
Matt

Thanks for letting me know that. As you said RTL8139/RTL8139C+
use different config registers and it may affect WOL functionality.
When I implemented WOL on rl(4), I remember WOL worked at that
time. After reading your mail, I wonder how it would have worked
at that time. :-(
Thanks.
