I currently have one -CURRENT machine, and several 6.2-STABLE machines. For
at least two of them (the -CURRENT and an x86 -STABLE machine) I'd really

both of them really do not need to be on all the time, but I want to be able
to reach them when I need a file from them when I'm elsewhere.

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

I usually use either if_em or if_xl chipsets, so I hoped landing this code
in at least -CURRENT (should go there first, I guess) would result in more
chipsets supported ;)

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".

If anyone has a card that does wake on lan after shutdown from Linux
but not after shutdown from FreeBSD with my patch applied let me know.
You may need to use the ethtool utility to enable WOL on Linux.

I don't run Linux on either machine. Perhaps I could do some tests on my
workstation with a CD-based linux distribution.

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