Hi all,

I am new to DPDK. I found 2 functions that can send packets:
rte_eth_tx_buffer and rte_eth_tx_burst. I am confused about why we need
these two different functions. To me, I can use only rte_eth_tx_burst, and
rte_eth_tx_buffer does add more functional capability. Are there any other
concerns like performance or others that we need these two functions?
