This feature adds vhost pmd extended statistics from per port perspective in order to meet the requirements of the applications such as OVS etc. RX/TX xstats count the bytes without CRC. This is different from physical NIC stats with CRC. The statistics counters are based on RFC 2819 and RFC 2863 as follows: rx/tx_good_packets rx/tx_total_bytes rx/tx_missed_pkts rx/tx_broadcast_packets rx/tx_multicast_packets rx/tx_unicast_packets rx/tx_undersize_errors rx/tx_size_64_packets rx/tx_size_65_to_127_packets; rx/tx_size_128_to_255_packets; rx/tx_size_256_to_511_packets; rx/tx_size_512_to_1023_packets; rx/tx_size_1024_to_1522_packets; rx/tx_1523_to_max_packets; rx/tx_errors rx_fragmented_errors rx_jabber_errors rx_unknown_protos_packets; No API is changed or added. rte_eth_xstats_get_names() to retrieve what kinds of vhost xstats are supported, rte_eth_xstats_get() to retrieve vhost extended statistics, rte_eth_xstats_reset() to reset vhost extended statistics. The usage of vhost pmd xstats is the same as virtio pmd xstats. for example, when test-pmd application is running in interactive mode vhost pmd xstats will support the two following commands: show port xstats all | port_id will show vhost xstats clear port xstats all | port_id will reset vhost xstats net/virtio pmd xstats(the function virtio_update_packet_stats) is used as reference when implementing the feature.
