diff
1. startup counsumer thread(main_loop) call rte_eth_rx_burst.
but the real rx_burst is dummy_eth_rx_burst
2. call rte_eth_dev_start: will startup dev and expose selection of PMD
fast-path functions
3. get xstats by name("rx_missed_errors"), maybe see misserr greater than 0
my solution：
expose selection of PMD fast-path functions before dev_start
(rte_eth_dev_start)
