Re: [libvirt] [PATCH] nwfilter: fix tear down order and consolidate functions

To avoid race-conditions, the tear down of a filter has to happen before the tap interface disappears and another tap interface with the same name can re-appear. This patch tries to fix this. In one place, where communication with the qemu monitor may fail, I am only tearing the filters down after knowing that the function did not fail. I am also moving the tear down functions into an include file for other drivers to reuse.
