Subject: [PATCH v2 2/2] mempool:pktmbuf pool default fallback for mempool ops error
Date: Thu, 15 Sep 2016 22:43:27 +0530	[thread overview]
Message-ID: <1473959607-1951-2-git-send-email-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <1473959607-1951-1-git-send-email-hemant.agrawal@nxp.com>

In the rte_pktmbuf_pool_create, if the default external mempool is
not available, the implementation can default to "ring_mp_mc", which
is an software implementation.
