that is only fine when the mtu is 64K or when mtu is not negotiated. Because in spec we have "The device MUST NOT pass received packets that exceed mtu (plus low level ethernet header length) size with gso_type NONE or ECN after VIRTIO_NET_F_MTU has been successfully negotiated." We need to update the definition of those gso counter to indicate above two conditions. --------------------------------------------------------------------- To unsubscribe, e-mail: virtio-dev-unsubscr...@lists.oasis-open.org For additional commands, e-mail: virtio-dev-h...@lists.oasis-open.org
