[Qemu-devel] [PULL 14/14] tests: add test cases for netfilter object

[Jason Wang <jasowang@redhat.com>]

From: Yang Hongyang <yanghy@cn.fujitsu.com>

Using qtest qmp interface to implement following cases:
1) add/remove netfilter
2) add a netfilter then delete the netdev
3) add/remove more than one netfilters
4) add more than one netfilters and then delete the netdev
