As a example to use ptype info, l3fwd needs firstly to use rte_eth_dev_get_supported_ptypes() API to check if device and/or its PMD driver will parse and fill the needed packet type; if not, use the newly added option, --parse-ptype, to analyze it in the callback softly. As the mode of EXACT_MATCH uses the 5 tuples to caculate hash, so we narrow down its scope to: a. ip packets with no extensions, and b. L4 payload should be either tcp or udp. Note: this patch does not completely solve the issue, "cannot run l3fwd on virtio or other devices", because hw_ip_checksum may be not supported by the devices. Currently we can: a. remove this requirements, or b. wait for virtio front end (pmd) to support it.
