Subject: [dpdk-dev] [PATCH] vhost: fix batch enqueue only handle few packets
Date: Thu, 7 Nov 2019 22:37:48 +0800 [thread overview]
Message-ID: <20191107143748.20649-1-yong.liu@intel.com> (raw)
After enqueue function finished, packet index has been increased. Batch
enqueue function should retrieve mbuf structure pointed by that index.
