dpdk: tx/rx burst function description refactor
DPDK provides two new APIs to retrieve information about the Tx/Rx
packet burst mode:
rte_eth_tx_burst_mode_get
rte_eth_rx_burst_mode_get
This patch leverages these two APIs to describe the tx/rx mode.
Currently, Intel X710/E810 and Mellanox Mlx5 support the new APIs.
For NICs that don't support the new APIs, still use the original way
to print their tx/rx function name
Type: refactor
