Offload State Structures

[The TCP chimney offload feature is deprecated and should not be used.]

The following table indicates which structures a host stack uses to package offload state.

State layer	Variables	Structure
Neighbor	Constant	NEIGHBOR_OFFLOAD_STATE_CONST
	Cached	NEIGHBOR_OFFLOAD_STATE_CACHED
	Delegated	NEIGHBOR_OFFLOAD_STATE_DELEGATED
Path	Constant	PATH_OFFLOAD_STATE_CONST
	Cached	PATH_OFFLOAD_STATE_CACHED
	Delegated	PATH_OFFLOAD_STATE_CACHED
TCP	Constant	TCP_OFFLOAD_STATE_CONST
	Cached	TCP_OFFLOAD_STATE_CACHED
	Delegated	TCP_OFFLOAD_STATE_DELEGATED

When passed between the host stack and the offload target, an offload state structure is always associated with an offload block list.
