[dpdk-dev] [PATCH v5 1/3] security: add anti replay window size

[Hemant Agrawal]

At present the ipsec xfrom is missing the important step
to configure the anti replay window size.
The newly added field will also help in to enable or disable
the anti replay checking, if available in offload by means
of non-zero or zero value.
