Subject: [PATCH 157/268] vhost-user: add Net prefix to internal state
structure
RH-Author: plai@redhat.com
Message-id: <1529607285-9942-2-git-send-email-plai@redhat.com>

O-Subject: [RHEL7.6 PATCH BZ 1526645 01/10] vhost-user: add Net prefix to internal state structure
Bugzilla: 1526645
RH-Acked-by: Michael S. Tsirkin <mst@redhat.com>
RH-Acked-by: Maxime Coquelin <maxime.coquelin@redhat.com>
RH-Acked-by: Laurent Vivier <lvivier@redhat.com>
From: Tiwei Bie <tiwei.bie@intel.com>
We are going to introduce a shared vhost user state which
will be named as 'VhostUserState'. So add 'Net' prefix to
the existing internal state structure in the vhost-user
netdev to avoid conflict.
