To enable Wake-On-Lan (WOL) on your hda:HDA
1. Enable WOL in the BIOS
4. Look for a line similar to this:
<code> Wake-on: g</code>
This means that WOL by magic packets is enabled on that interface.
If the line is
<code> Wake-on: d</code>
then WOL is disabled. Activate it by running <code>ethtool -s eth1 wol g</code>
