[Xen-devel] [PATCH 4/4] xen: Fix PV-on-HVM

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

In the context of PV-on-HVM under Xen, the emulated nics are supposed to be
unplug before the guest drivers are initialized. This mean that there must be
unplug without the consent of the guest.

Without this patch, the guest end up with two nics with the same MAC, the
emulated nic and the PV nic.
