In this unit test we will test the mirror function.
start qemu with:
-netdev socket,id=qtest-bn0,fd=sockfd
-device e1000,netdev=qtest-bn0,id=qtest-e0
-chardev socket,id=mirror0,path=/tmp/filter-mirror-test.sock,server,nowait
-object filter-mirror,id=qtest-f0,netdev=qtest-bn0,queue=tx,outdev=mirror0
We inject packet to netdev socket id = qtest-bn0,
filter-mirror will copy and mirror the packet to mirror0.
we read packet from mirror0 and then compare to what we injected.
