In order to unify the packet type, the field of 'packet_type' in 'struct rte_mbuf' needs to be extended from 16 to 32 bits. Accordingly, some fields in 'struct rte_mbuf' are re-organized to support this change for Vector PMD. As 'struct rte_kni_mbuf' for KNI should be right mapped to 'struct rte_mbuf', it should be modified accordingly. In ixgbe PMD driver, corresponding changes are added for the mbuf changes, especially the bit masks of packet type for 'ol_flags' are replaced by unified packet type. In addition, more packet types (UDP, TCP and SCTP) are supported in vectorized ixgbe PMD. To avoid breaking ABI compatibility, all the changes would be enabled by RTE_NEXT_ABI. Note that around 2% performance drop (64B) was observed of doing 4 ports (1 port per 82599 card) IO forwarding on the same SNB core.
