[dpdk-dev] [PATCH v6 3/7] test/ring: fix wrong size used in memcmp
From: Feifei Wang <hidden>

When using memcmp function to check data, the third param should be the
size of all elements, rather than the number of the elements.
Fixes: a9fe152363e2 ("test/ring: add custom element size functional tests")
