Subject: [PATCH 1/2] vdpasim: fix MAC address configuration
Date: Thu, 29 Oct 2020 13:20:49 +0100 [thread overview]
Message-ID: <20201029122050.776445-2-lvivier@redhat.com> (raw)
In-Reply-To: <20201029122050.776445-1-lvivier@redhat.com>
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.
Fixes: 2c53d0f64c06 ("vdpasim: vDPA device simulator")
