This clamps the maximum segment size on the TCP negotiation when addressing remote clusters with OVN. With the OVN implementation we have an issue where the need-frag ICMPs used for PMTU discovery are sent into the wront interface by the kernel, this limits the scope of the issue, although it introduces a performance penalty for jumboframe capable networks.
