> Currently each rte_node registers separate mbuf dynamic fields for their

> a particular node, the registered dynamic field(by that node) is no
> longer used.
> 
> This patch series adds a global/common mbuf dynamic field which is
> reusable by all the nodes(including out-of-tree nodes). This helps to
> repurpose same mbuf dynamic field for other nodes. It contains two types
> of fields: (a) persistent (b) overloadable.

> are no persistent fields added but they can be added later
> 
> Overloadable fields are those which can be used by two adjacent nodes.
> Same overloadable fields can be repurposed by other two adjacent nodes.

> This patch series also updates ip4/ip6 lookup/rewrite nodes to use
> overlaodable mbuf dynamic fields.
