include: attempt to document device_class_set_props
I'm still not sure how I achieve by use case of the parent class
defining the following properties:
static Property vud_properties[] = {
DEFINE_PROP_CHR("chardev", VHostUserDevice, chardev),
DEFINE_PROP_UINT16("id", VHostUserDevice, id, 0),
DEFINE_PROP_UINT32("num_vqs", VHostUserDevice, num_vqs, 1),
DEFINE_PROP_END_OF_LIST(),
};
But for the specialisation of the class I want the id to default to
the actual device id, e.g.:
static Property vu_rng_properties[] = {
DEFINE_PROP_UINT16("id", VHostUserDevice, id, VIRTIO_ID_RNG),
DEFINE_PROP_UINT32("num_vqs", VHostUserDevice, num_vqs, 1),
DEFINE_PROP_END_OF_LIST(),
};
And so far the API for doing that isn't super clear.
