From 566de3dd20df4a4d7d68091e934f59a8849e678c Mon Sep 17 00:00:00 2001
From: Szymon Sliwa <szs@semihalf.com>
Date: Wed, 31 Jan 2018 14:51:23 +0100
Subject: [PATCH 3/4] [HACK] enable inline in dpdk pktio
Added simple lines which enable IPsec inline mode
on RX using dpdk pktio. The changes are not intended to be
pushed to main odp repository - these are only minimal changes
to make use of the functionality.
