[dpdk-dev] [PATCH v6 16/18] examples/l3fwd-power: replace bit mask based packet type with unified packet type

[Helin Zhang]

To unify packet types among all PMDs, bit masks of packet type for
'ol_flags' are replaced by unified packet type.
To avoid breaking ABI compatibility, all the changes would be
enabled by RTE_UNIFIED_PKT_TYPE, which is disabled by default.
