"ID_PATH" is.<br>

Also, you do not need to use Property for your match, it is just<br>
<br>
[Match]<br>
Path=pci-0000:01:00.0<br>
Driver=igb<br></blockquote><div><br></div><div>I'll experiment further with the "Property=" option since the "Path" does not include the bus ID which I need to match on.  <br></div><div><br></div><div>Thank you for pointing out my misunderstanding of the documentation. <br></div><div><br></div><div>Kind regards</div><div>Henti<br></div></div></div>
