Subject: [dpdk-dev] [PATCH v2 3/5] mbuf: support register mempool Hw ops name APIs
Date: Mon, 15 Jan 2018 11:41:12 +0530	[thread overview]
Message-ID: <1515996674-26338-4-git-send-email-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <1515996674-26338-1-git-send-email-hemant.agrawal@nxp.com>

With this patch the specific HW mempool are no longer required to be
specified in the config file at compile. A default platform hw mempool
can be detected dynamically and published to config at run time.
Only one type of HW mempool can be active default.
