Subject: [dpdk-dev] [PATCH v3 5/5] net/iavf: fix vector mapping with queue
Date: Thu,  7 Jan 2021 16:27:18 +0800
Message-ID: <20210107082718.33748-6-jingjing.wu@intel.com> (raw)
In-Reply-To: <20210107082718.33748-1-jingjing.wu@intel.com>

Fix the vector mapping with queue by changing the recircle when
exceeds RX_VEC_START + nb_msix;

Fixes: d6bde6b5eae9 ("net/avf: enable Rx interrupt")
