Rx missed is used by hardware devices to indicate the packets that driver could not receive because of lack of resources. It has to come from the hardware (or maybe the host in a virtual driver). There probably is not an analogous counter in memif because it would have to be maintained by the other side (sender) and then have a control API for it. If it is your application, then the sending side could report how many times tx_burst was unable to send packets.
