> Currently the length of an indirect descriptor is limited to the ringsize (so even without indirect descriptors, you'd always make progress).  This is a limitation for some proposed devices, eg virtio-gl.
> We probably need some limit (eg. vhost has IOV_MAX = 1024), but perhaps it should be an independent queue parameter.
