Subject: [dpdk-dev] [PATCH v5 4/5] net/fm10k: fix vector rx burst for fm10k
Date: Fri, 16 Oct 2020 17:44:30 +0800	[thread overview]
Message-ID: <20201016094431.96889-5-jia.guo@intel.com> (raw)
In-Reply-To: <20201016094431.96889-1-jia.guo@intel.com>

The scattered receive path should use a wrapper function to achieve the
goal of burst maximizing.

Bugzilla ID: 516
Fixes: fe65e1e1ce61 ("fm10k: add vector scatter Rx")

Signed-off-by: Jeff Guo <jia.guo@intel.com>
