[dpdk-dev] [PATCH v8 08/18] vmxnet3: replace bit mask based packet type with unified packet type

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_NEXT_ABI, which is disabled by default.
