Subject: [dpdk-dev] [PATCH] net/iavf: fix vector mapping with queue
Date: Thu, 28 Jan 2021 10:37:24 +0800 [thread overview]
Message-ID: <20210128023724.39057-1-jingjing.wu@intel.com> (raw)
Fix the vector mapping with queue by changing the recircle when
exceeds RX_VEC_START + nb_msix;
Fixes: d6bde6b5eae9 ("net/avf: enable Rx interrupt")
