ProtocolUpdateOffloadComplete routine

NDIS calls a protocol driver's or intermediate driver's ProtocolUpdateOffloadComplete function to complete an update offload operation that the driver previously initiated by calling the NdisUpdateOffload function.

Syntax


UPDATE_OFFLOAD_COMPLETE_HANDLER ProtocolUpdateOffloadComplete;

VOID ProtocolUpdateOffloadComplete(
  _In_  NDIS_HANDLE ProtocolBindingContext,
  _In_  PNDIS_PROTOCOL_OFFLOAD_BLOCK_LIST OffloadBlockList
)
{ ... }

Parameters

ProtocolBindingContext [in]

A handle to a context area allocated by the protocol driver. The driver maintains the per binding context information in this context area. The driver supplied this handle to NDIS when the driver called the NdisOpenAdapterEx function

OffloadBlockList [in]

A pointer to an NDIS_PROTOCOL_OFFLOAD_BLOCK_LIST structure that can be a stand-alone structure or the root of a linked list of such structures. These structures identify the state that was updated or that was attempted to be updated.

Return value

None

Remarks

In response to an underlying offload target's or intermediate driver's call to the NdisMUpdateOffloadComplete function, NDIS calls a protocol or intermediate driver's ProtocolUpdateOffloadComplete function.

An intermediate driver must propagate the completion of the update offload operation to the driver above it by calling NdisMUpdateOffloadComplete. For more information, see Propagating the Completion of a State-Manipulation Operation.

From the NDIS_PROTOCOL_OFFLOAD_BLOCK_LIST structure that was passed to its ProtocolUpdateOffloadComplete function, the intermediate driver constructs an NDIS_MINIPORT_OFFLOAD_BLOCK_LIST structure. For more information, see Reusing an NDIS_PROTOCOL_OFFLOAD_BLOCK_LIST Structure. When calling the NdisMUpdateOffloadComplete function, the intermediate driver passes a pointer (the OffloadBlockList parameter) to this newly constructed NDIS_MINIPORT_OFFLOAD_BLOCK_LIST structure.
