Subject: [dpdk-dev] [PATCH v6 4/4] app/testpmd: add mempool bulk get for txonly mode
Date: Tue, 2 Apr 2019 09:53:36 +0000	[thread overview]
Message-ID: <20190402095255.848-4-pbhagavatula@marvell.com> (raw)
Message-ID: <20190402095336.14d2tf5gLT4g9RQexjQmRJzfYuZmAHKO075Nz0ulxVo@z> (raw)
In-Reply-To: <20190402095255.848-1-pbhagavatula@marvell.com>

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Use mempool bulk get ops to alloc burst of packets and process them.
If bulk get fails fallback to rte_mbuf_raw_alloc.

Tested-by: Yingya Han <yingyax.han@intel.com>
Suggested-by: Andrew Rybchenko <arybchenko@solarflare.com>
