As Alex explained in the internal mail thread, the device ID is not related
to pseudo MAC vs physic MAC. The device ID 0xe110 is used for switch
management port, and the device ID 0xe101 is used for non-management
port. So the current patch is fine, the only thing that needs improvement is
to include this in the commit message to avoid causing the same confusion
for others as I have.
