You could save one allocation (and get better cache locality)
by using a dynamic array here.
struct reader {
struct {
int fd;
uint32_t mtu;
uint32_t burst_size;
struct rte_mempool *mempool;
} params;
struct rte_swx_port_in_stats stats;
uint32_t n_pkts;
uint32_t pos;
struct rte_mbuf *pkts[];
};
Then change the allocation to size it based on number of packets.
