 Just an interesting note about this issue:
 
 I noticed that Linux suffers from the same problem. The Linux driver
 is somehow able to proceed even though getting the mac address
 fails. Therefore this Xen bug/feature does not cause headaches
 there, even though we need a workaround in FreeBSD driver.
 
 Have a look at Red Hat's virtualization guide:
 
 http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/sect-Virtualization-Troubleshooting_the_Xen_para_virtualized_drivers-Verifying_the_para_virtualized_drivers_have_successfully_loaded.html
 
 There you will see the following line:
 
 vif vif-0: 2 parsing device/vif/0/mac
 
 ...which is an indication of this very same error condition. 
 
 However according to the Red Hat documentation this just means that
 the PV drivers have successfully loaded :).
