From 4a6a42db53aae049a8a64d4b273761bc80c46ebf Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Thu, 29 Oct 2020 13:20:49 +0100 Subject: vdpasim: fix MAC address configuration vdpa_sim generates a ramdom MAC address but it is never used by upper layers because the VIRTIO_NET_F_MAC bit is not set in the features list. Because of that, virtio-net always regenerates a random MAC address each time it is loaded whereas the address should only change on vdpa_sim load/unload. Fix that by adding VIRTIO_NET_F_MAC in the features list of vdpa_sim.
