This option alters the behavior of onload_ordered_epoll_wait(). This function would normally ensure correct ordering across multiple interfaces. However, this impacts latency, as only events arriving before the first interface polled can be returned and still guarantee ordering.

If the traffic being ordered is only arriving on a single interface then this additional constraint is not necessary. When this option is enabled, traffic will only be ordered relative to other traffic arriving on the same interface.
