Unlike Linux which has a predetermined set of steps in processing packets.
DPDK is a raw toolkit where the processing is composed totally by the
network application.
Therefore DPDK has a raw eBPF library, it is up to the application to install it where
it wants in the packet processing. One example is done via rx and tx callbacks
as shown in the rte_bpf_ethdev.h.
