It's not documented anywhere. Much of these internal workings are not  
documented anywhere other than the implementation (and sometimes not  
even there).

If the device in question has a GLDv3 driver, then yes (but see  
6592059, which means that it doesn't work for wireless NICs).

For Christian, it won't work for a PV guest (or HVM with PV drivers),  
because his NICs are either wireless (wpi) or use a DLPI driver  
(skge). HVM domains access the NIC (or VNIC) using libdlpi whereas PV  
domains have a layered kernel driver (xnbo), which leads to this  
inconsistency.

In principle, yes. See above.

Note that 6592059 is currently low priority. If fixing this would  
help someone out we can do it relatively easily - the changes are  
understood.
