+Subject: [PATCH] virtio: enable indirect descriptors feature
+
+Virtio indirect descriptors are supported by the data-path
+but the feature bit is never set during feature negociation.
+
+This patch simply adds VIRTIO_RING_F_INDIRECT_DESC back to
+the supported features bit mask, hence enabling the use of
+indirect descriptors when the feature is negociated with the
+device.
