Subject: [dpdk-dev] [RFC 08/19] vhost: initialize vrings IOTLB caches
Date: Tue,  4 Jul 2017 11:49:11 +0200	[thread overview]
Message-ID: <20170704094922.11405-9-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20170704094922.11405-1-maxime.coquelin@redhat.com>

The per-virtqueue IOTLB cache init is done at virtqueue
init time. init_vring_queue() now takes vring id as parameter,
so that the IOTLB cache mempool name can be generated.
