+ # Packet ordering method for asynchronous IPsec processing
+ #
+ # Asynchronous IPsec processing maintains original packet order when
+ # started within ordered or atomic scheduling context. In addition
+ # to that, ODP API specifies that the order of IPsec processing
+ # (i.e. anti-replay window update and sequence number generation)
+ # is the same as the original packet order.
+ #
+ # The following settings control how the order is maintained in
+ # asynchronous IPsec operations. They have no effect on synchronous
+ # operations where the ODP application is responsible of the ordering.
+ #
+ # Values:
+ #
+ # 0: Ordering is not attempted.
+ #
+ # This has the lowest overhead and the greatest parallelism but
+ # is not fully compliant with the API specification.
+ #
+ # Lack of ordering means that outbound IPsec packets, although
+ # remaining in the correct order, may have their sequence numbers
+ # assigned out of order. This can cause unexpected packet loss if
+ # the anti-replay window of the receiving end is not large enough
+ # to cover the possible misordering.
+ #
+ # Similarly, since anti-replay check is not done in the reception
+ # order, the anti-replay check sees additional packet misordering
+ # on top of the true misordering of the received packets. This
+ # means that a larger anti-replay window may be required to avoid
+ # packet loss.
+ #
+ # 1: Ordering by waiting
+ #
+ # Correct processing order is maintained by a simple mechanism
+ # that makes a thread wait until its scheduling context has
+ # reached the head of its input queue.
+ #
+ # This limits parallelism when single input queue is used, even
+ # when packets get distributed to multiple SAs.
