This is not enough, as some NIC hardware can recognize quite a lot of packet types, e.g i40e hardware can recognize more than 150 packet types. Hiding those packet types hides hardware offload capabilities which could be quite useful for improving performance and for end users. So an unified packet types are needed to support all possible PMDs. A 16 bits packet_type in mbuf structure can be changed to 32 bits and used for this purpose. In addition, all packet types stored in ol_flag field should be deleted at all, and 6 bits of ol_flags can be save as the benifit. Initially, 32 bits of packet_type can be divided into several sub fields to indicate different packet type information of a packet. The initial design is to divide those bits into fields for L2 types, L3 types, L4 types, tunnel types, inner L2 types, inner L3 types and inner L4 types. All PMDs should translate the offloaded packet types into these 7 fields of information, for user applications. v2 changes: * Enlarged the packet_type field from 16 bits to 32 bits. * Redefined the packet type sub-fields. * Updated the 'struct rte_kni_mbuf' for KNI according to the mbuf changes. * Used redefined packet types and enlarged packet_type field for all PMDs and corresponding applications. * Removed changes in bond and its relevant application, as there is no need at all according to the recent bond changes.
