XDP statistics are reported in ethtool, in total and per ring, as follows: - xdp_drop: the number of packets dropped by xdp. - xdp_tx: the number of packets forwarded by xdp. - xdp_tx_full: the number of times an xdp forward failed due to a full tx xdp ring. In addition, all packets that are dropped/forwarded by XDP are no longer accounted in rx_packets/rx_bytes of the ring, so that they count traffic that is passed to the stack.
