Setting 16 Bytes Rx Descriptor Size

For better small packet size performance, setting 16 bytes Rx descriptor is recommended. It can be set from the top-level DPDK directory:

For an l3fwd application, DPDK meson build settings could be used to set Rx descriptors to 16:

CC=gcc meson -Dlibdir=lib -Dexamples=l3fwd -Dc_args=-DRTE_LIBRTE_ICE_16BYTE_RX_DESC --default-library=static x86_64-nativelinuxapp-gcc
