            Bug ID: 226763
           Summary: Wake on lan (WOL_MAGIC) stopped working with re nic
           Product: Base System
           Version: 11.1-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern

Yesterday I upgraded this box from 10.3-RELEASE to 11.1-RELEASE. With
10.3-RELEASE, wake on lan worked perfectly. I had enabled it with 'ifconfig re0
wol_magic', then after doing 'poweroff' i could wake the box with the
'wakeonlan' command from an linux (ubuntu) box. Sadly, after the upgrade to
11.1-RELEASE this no longer worked.
