Subject: [dpdk-dev] [PATCH 19/28] vhost: add index field in vhost virtqueues
Date: Wed, 19 Jun 2019 18:14:44 +0300 [thread overview]
Message-ID: <1560957293-17294-20-git-send-email-ndragazis@arrikto.com> (raw)
In-Reply-To: <1560957293-17294-1-git-send-email-ndragazis@arrikto.com>
From: Stefan Hajnoczi <stefanha@redhat.com>
Currently, the only way of determining a struct vhost_virtqueue's index
is to search struct virtio_net->virtqueue[] for its address. Stash the
index in struct vhost_virtqueue so we won't have to search the array.
This new field will be used by virtio-vhost-user.
