Subject: [dpdk-dev] [PATCH v2] app/testpmd: fix IP checksum calculation
Date: Fri, 4 Dec 2020 23:42:38 -0600 [thread overview]
Message-ID: <20201205054238.12469-1-prekageo@amazon.com> (raw)
In-Reply-To: <20201203135954.1127-1-prekageo@amazon.com>
Strict-aliasing rules are violated by cast to uint16_t* in flowgen.c
and the calculated IP checksum is wrong on GCC 9 and GCC 10.
Signed-off-by: George Prekas <prekageo@amazon.com>

v2:
* Instead of a compiler barrier, use a compiler flag.
