The buffer index allows downstream consumers of these data to easily filter/track single packets as they traverse the forwarding graph. FWIW, the 32-bit buffer index is stored in big endian format. As of this writing, major version = 1, minor version = 0. Nstrings will be either 4 or 5. Here is the current set of protocol hints: typedef enum { VLIB_NODE_PROTO_HINT_NONE = 0, VLIB_NODE_PROTO_HINT_ETHERNET, VLIB_NODE_PROTO_HINT_IP4, VLIB_NODE_PROTO_HINT_IP6, VLIB_NODE_PROTO_HINT_TCP, VLIB_NODE_PROTO_HINT_UDP, VLIB_NODE_N_PROTO_HINTS, } vlib_node_proto_hint_t; Example: VLIB_NODE_PROTO_HINT_IP6 means that the first octet of packet data SHOULD be 0x60, and should begin an ipv6 packet header.

2018-11-15ip4-input: fix prefetch data issue for tunnel decap casesZhiyong Yang1-4/+8
There are two reasons to modify the existing code ip4_input_inline. 1. For many tunnel decap cases, inner ip header or its part is possible in the second cacheline, not first cacheline only after the field "data", and this will cause data cache miss once the second cacheline is needed to access. e.g vxlan-gpe. 2. For most of cases, "data" is the starting address of ethernet header, not IP header. The existing code causes misunderstanding from code readability perspective.
