It looks like this should also fix an issue I've been having with BGP-routed requests to pods, where reply packets from pods don't hit the "early accept" rules from kube-ovn, and instead go through the KUBE-FORWARD chain where they get dropped.

Any idea when this fix might make it out to a stable release?
