networking-sfc doesn't change table flows after vnf has been migrated

[TianZhang He]

Start with:
VNFFG/SFC: Client->VNF1->Server in one compute node (compute0)

nova live-migration --block-migrate $VDU-name-of-VNF1 $dst_node

After Live migration VNF1 from compute0 to compute1:
VNFFG/SFC: Client(compute0)->VNF1(compute1)->Server(compute0)

The port chain created by Tacker by using networking-sfc is not updated as checking the flow tables in br-int. Therefore, the VNFFG is broken.

I don't think we can do it now. You can do it with these steps: delete VNFFG --> migrate VNFs --> re-create VNFFG.
