Subject: [dpdk-dev] [PATCH v3 4/5] test/mbuf: enhance mbuf refcnt test
Date: Tue, 31 Mar 2015 21:23:03 +0200	[thread overview]
Message-ID: <1427829784-12323-5-git-send-email-zer0@droids-corp.org> (raw)
In-Reply-To: <1427829784-12323-1-git-send-email-zer0@droids-corp.org>

From: Olivier Matz <olivier.matz@6wind.com>

Check that the data in the cloned mbuf is the same than in the
reference mbuf.
Check that the reference counter is incremented for each segment.
