OVS should call into CT NAT for packets of new expected connections only when the conntrack state is persisted with the 'commit' option to the OVS CT action. The test for this condition is doubly wrong, as the CT status field is ANDed with the bit number (IPS_EXPECTED_BIT) rather than the mask (IPS_EXPECTED), and due to the wrong assumption that the expected bit would apply only for the first (i.e., 'new') packet of a connection, while in fact the expected bit remains on for the lifetime of an expected connection. The 'ctinfo' value IP_CT_RELATED derived from the ct status can be used instead, as it is only ever applicable to the 'new' packets of the expected connection.
