Also they help find out if packets are leaked, as if "sent != success + fail", there are probably packets never freed up properly. NOTE: if bisect brought you here, you should apply the series up until "xen-netback: Timeout packets in RX path", otherwise Windows guests can't work properly and malicious guests can block other guests by not releasing their sent packets.
