--- Comment #4 from Eric van Gyzen <vangyzen@freebsd.org> ---
I get the same behavior as Guido.  I'm running head r297219 (24 March) on a
Dell XPS 8900 with an onboard NIC.  To send the WOL packet, I run this on a
neighboring 10.2-RELEASE machine:

    wake bridge0 64:00:6a:80:be:cd

As I mentioned in the mail thread:  In em_get_wakeup(), the eeprom_data is
zero, so adapter->wol stays zero, so ifconfig doesn't show any WOL
capabilities.  When I ignore the eeprom_data by commenting out the "if"
condition, WOL capabilities appear in ifconfig.  However, even when I enable
WOL with ifconfig, WOL still doesn't work after a "shutdown -p now".
