Detailed Description
rte_node specific mbuf dynamic field structure [rte_node_mbuf_dynfield_t]
It holds two types of fields:
- 1.
Persistent fields: Fields which are preserved across nodes during graph walk.
- ·
Eg: rx/tx interface etc
- 2.
Overloadable fields: Fields which can be repurposed by two adjacent nodes.

Field Documentation
rte_node_mbuf_overload_fields_t overloadable_data
Overloadable mbuf fields across graph walk. Fields which can change.
Two adjacent nodes (producer, consumer) can use this memory region for sharing per-mbuf specific information. Once mbuf leaves a consumer node, this region can be repurposed by another sets of [producer, consumer] node.
In fast path, this region can be accessed by rte_node_mbuf_overload_fields_get().
