Yes, wake on lan, if used properly, makes computers a bit more
friendly to the environment :-)

There is code for enabling wake on lan in the Linux drivers for both
if_xl and if_em cards. See drivers/net/3c59x.c and
drivers/net/e1000/e1000_ethtool.c in the linux source tree.

So I don't think adding support for these cards is a problem.
Just need to find some time to do it...

If anyone has data sheets for these cards I'd like a copy if possible.

By the way if anyone has data sheets for if_vr I'd like a copy as
well please because there is something the Linux driver does that
I do not understand because the code is not obvious enough.
Specifically I need to understand what the hell they mean exactly
by "patterns for WOL".

No need to test your cards with Linux since we know now there is code
for this in Linux so it should work anyway.
