[Qemu-devel] [PATCH] xen-platform: Cleanup network infrastructure when emulated NICs are unplugged

[Ross Lagerwall]

When the guest unplugs the emulated NICs, call net_cleanup() to cleanup
the network infrastructure in QEMU as it is not needed anymore. Most
importantly, this allows the tap interfaces which QEMU holds open to be
closed and removed.
