[dpdk-dev] [PATCH v9 14/19] examples/ip_reassembly: replace bit mask based packet type with unified packet type

Fri Jul 3 10:32:22 CEST 2015


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.
