I figured that might be the case. Yes I would've disabled the VPN if I didn't get driver errors. I changed the network interface to use an emulated Intel E1000 tonight, and if I bypass the VPN it works as it should. > I guess we should be more flexible about which hooks we support, so it > can also be used on devices with no XDP support.

At least that's what I remember being the issue when I tested CAKE's autorate-ingress back in the day. - Nils >> -Toke
