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 like to have WoL support, as these are my workstation and a home
server, 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

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 ;)

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