High Performance of Small Packets on 100G NIC- Use 16 Bytes Rx Descriptor Size

ICE PMD supports both 16 and 32 bytes Rx descriptor sizes. The 16 bytes size can provide high performance at small packet sizes. Configuration of CONFIG_​RTE_​LIBRTE_​ICE_​16BYTE_​RX_​DESC in config files can be changed to use 16 bytes size Rx descriptors.

More details to set 16 bytes Rx descriptor size in Setting 16 Bytes Rx Descriptor Size.
