This test cases uses floating IP (FIP) addresses for each endpoint. If the destination is a FIP, the packet will undergo a transformation of the form (dst=FIP, src=non-FIP) --> (dst=non-FIP, src=FIP) before egress. Otherwise the packet is untouched.
This exercises the ct_clear action in the datapath.
