From 2f8f461888052f1b92ebe6419514355538f7cd68 Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Tue, 15 Dec 2020 15:42:45 +0100 Subject: vdpa_sim: add device id field in vdpasim_dev_attr 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.
