Memset here is unnecessary since only caller is rte_eth_stats_get()
which already did memset
int
rte_eth_stats_get(uint8_t port_id, struct rte_eth_stats *stats)
{
struct rte_eth_dev *dev;
RTE_ETH_VALID_PORTID_OR_ERR_RET(port_id, -EINVAL);
dev = &rte_eth_devices[port_id];
memset(stats, 0, sizeof(*stats));
RTE_FUNC_PTR_OR_ERR_RET(*dev->dev_ops->stats_get, -ENOTSUP);
stats->rx_nombuf = dev->data->rx_mbuf_alloc_failed;
(*dev->dev_ops->stats_get)(dev, stats);

Ok. Will remove.
