Yeah, it's your patch that broke compat here which we applied already [0], but upstream hasn't yet [1] (do you know what's going on with them, much less responsive and no release yet since over three years, maybe just NVIDIA stifling the great work the cumulus devs?) anyhow, disabling accept_ra by default was IMO the right call.
