I assume you mean max(MTU) over all ports? We would have to replace the ring after each MTU change. Doing so in use is non trivial and expensive. The current frame size of 16K covers jumbo frames and is a sane default but can certainly be optimized further on, f.e. as we possibly extend OVS user space to handle GSO frames. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
