Subject: [PATCH v6 07/12] vdpa: add net_vhost_vdpa_cvq_info NetClientInfo
Date: Thu,  4 Aug 2022 20:17:17 +0200	[thread overview]
Message-ID: <20220804181722.701067-8-eperezma@redhat.com> (raw)
In-Reply-To: <20220804181722.701067-1-eperezma@redhat.com>

Next patches will add a new info callback to restore NIC status through
CVQ. Since only the CVQ vhost device is needed, create it with a new
NetClientInfo.

Signed-off-by: Eugenio Pérez <eperezma@redhat.com>
---
v5: Create a new NetClientInfo instead of reusing the dataplane one.
