From 2b0840f907a1e69f05a740a13df515dfa80ebf02 Mon Sep 17 00:00:00 2001
From: Szymon Sliwa <szs@semihalf.com>
Date: Thu, 22 Feb 2018 14:41:35 +0100
Subject: [PATCH 4/4] [HACK] enable inline for odp-dpdk
Added simple lines which enable IPsec inline mode
on RX using socket pktio. The changes are not intended to be
pushed to main odp repository - these are only minimal changes
to make use of the functionality.
