Maybe just add a hint to the manpage that WOL is possible broken?

Probably you want to poke jkim@ to address video resume issue. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
