Subject: [dpdk-dev] [PATCH v5 1/7] mempool/dpaa2: add functions exposed to DPDK applications
Date: Thu,  3 May 2018 22:03:47 +0530	[thread overview]
Message-ID: <1525365233-5956-2-git-send-email-nipun.gupta@nxp.com> (raw)
In-Reply-To: <1525365233-5956-1-git-send-email-nipun.gupta@nxp.com>

There are two API's which are required by NXP specific Command Interface
Application (AIOP CMDIF). This patch exposes these two API's.
