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 Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: Ibe47f5debe3b3f17f462fbf9834394e22845cc08
