So for NIC's which have such a kind of HW support, a new SA option is provided to indicate whether OOP needs to be enabled on that Inline ingress security session or not. Since for inline ingress sessions, packet is not received by CPU until the processing is done, we can only have per-SA option and not per-packet option like Lookaside sessions.
