  FreeBSD isn't disabling WOL. It needs to be enabled on shutdown
for most cards.

  I have patches for ifconfig, and the xl driver to enable WOL.

  It should be possible to add support to other drivers, but
it's different for each card.

  You should be able to find a diff against 5-stable in the archives.
Changes against -CURRENT aren't _that_ different.
