FreeBSD doesn't have any hooks in the NIC driver(s) (all of them) that
enables WOL after the machine shuts down.  It is a driver option that
enables that functionality and although there were patches written for a few
chipsets, nothing was implemented into the OS.

Put another way, there is zero support for WOL after you run FreeBSD, since
the FreeBSD driver does not include that hook.
