Subject: [dpdk-dev] [PATCH v2 5/5] net/fm10k: maximize vector rx burst for fm10k
Date: Thu, 27 Aug 2020 18:10:08 +0800 [thread overview]
Message-ID: <20200827101008.76906-6-jia.guo@intel.com> (raw)
In-Reply-To: <20200827101008.76906-1-jia.guo@intel.com>
The limitation of burst size in vector rx was removed, since it should
retrieve as much received packets as possible. And also the scattered
receive path should use a wrapper function to achieve the goal of
burst maximizing.
