How to distinguish RTE_ETH_FLOW_PKT_FILTER_IPV4_XX with
RTE_ETH_FLOW_NONFRAG_IPV4_XX, what is the difference?

There is also a patch http://dpdk.org/dev/patchwork/patch/9661/ which added
these fields. Maybe we can merge them together.

Why not use rte_eth_XX_flow directly but add a new one? Is it because of the
mask? If so, how about to add a field in rte_eth_fdir_input like:
struct rte_eth_fdir_input {
uint16_t flow_type;
union rte_eth_fdir_flow flow;
/**< Flow fields to match, dependent on flow_type */
union rte_eth_fdir_flow flow_mask;
struct rte_eth_fdir_flow_ext flow_ext;
/**< Additional fields to match */
};
Thanks
