Subject: [PATCH v4 07/18] vdpa_sim: add device id field in vdpasim_dev_attr
Date: Tue, 15 Dec 2020 15:42:45 +0100 [thread overview]
Message-ID: <20201215144256.155342-8-sgarzare@redhat.com> (raw)
In-Reply-To: <20201215144256.155342-1-sgarzare@redhat.com>
Remove VDPASIM_DEVICE_ID macro and add 'id' field in vdpasim_dev_attr,
that will be returned by vdpasim_get_device_id().
Use VIRTIO_ID_NET for vDPA-net simulator device id.
