_NDIS_HD_SPLIT_PARAMETERS structure

Description

The NDIS_HD_SPLIT_PARAMETERS structure defines the current header-data split settings of a miniport adapter.

Members

`Header`

The NDIS_OBJECT_HEADER structure for the provider characteristics structure (NDIS_HD_SPLIT_PARAMETERS). The driver sets the Type member of the structure that Header specifies to NDIS_OBJECT_TYPE_DEFAULT, the Revision member to NDIS_ HD_SPLIT_PARAMETERS_REVISION_1, and the Size member to NDIS_SIZEOF_HD_SPLIT_PARAMETERS_REVISION_1.

`HDSplitCombineFlags`

A set of flags that specify the current header-data split settings of a miniport adapter. A protocol driver or user-mode application can specify a bitwise OR of the following flags:

NDIS_HD_SPLIT_COMBINE_ALL_HEADERS

The miniport adapter should combine split frames. If header-data split is enabled in the hardware, the miniport driver should combine the header and data before indicating the frame to NDIS.

Remarks

The NDIS_HD_SPLIT_PARAMETERS structure is used in the OID_GEN_HD_SPLIT_PARAMETERS OID set request to specify the current header-data split settings of a miniport adapter.
