SYNOPSIS

#include <rte_node_mbuf_dynfield.h>

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().
