Flags

This member is reserved and must be set to 0 by the client. It is ignored by the provider.

MatchProfileId

This value is used to determine if the HeaderGroupMatchArray members describe an NDIS_GFP_HEADER_GROUP_EXACT_MATCH array or a NDIS_GFP_HEADER_GROUP_WILDCARD_MATCH array.

Priority

The priority of this filter.

CounterHandle

A handle to a counter.

TargetReceiveQueue

The target receive queue to filter.

RxFilterContext

The context for the receive filter.

HeaderGroupMatchArray

An array of either NDIS_GFP_HEADER_GROUP_EXACT_MATCH or NDIS_GFP_HEADER_GROUP_WILDCARD_MATCH elements as determined by the MatchProfileId member.

HeaderGroupMatchArrayNumElements

The number of elements for the HeaderGroupMatchArray.

HeaderGroupMatchArrayElementSize

The size of each element for the HeaderGroupMatchArray.

HeaderGroupMatchArrayTotalSize

The total size of the HeaderGroupMatchArray.

Remarks

This structure must be aligned on an 8-byte boundary.
