NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES_INIT function (netadapter.h)

The NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES_INIT function initializes a NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES structure.

Syntax

void NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES_INIT(
  [_Out_] NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES *GsoCapabilities,
  [_In_]  NET_ADAPTER_OFFLOAD_LAYER3_FLAGS     Layer3Flags,
  [_In_]  NET_ADAPTER_OFFLOAD_LAYER4_FLAGS     Layer4Flags,
  [_In_]  SIZE_T                               MaximumOffloadSize,
  [_In_]  SIZE_T                               MinimumSegmentCount,
  [_In_]  PFN_NET_ADAPTER_OFFLOAD_SET_GSO      EvtAdapterOffloadSetGso
);

Parameters

[_Out_] GsoCapabilities

A pointer to a driver-allocated NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES structure.

[_In_] Layer3Flags

Flags specifying the layer 3 protocols and variations contained in packets that the NIC can successfully segment.

[_In_] Layer4Flags

Flags specifying the layer 4 protocols and variations contained in packets that the NIC can successfully segment.

[_In_] MaximumOffloadSize

The maximum bytes of user data that the transport can pass to the NIC driver in a single packet.

[_In_] MinimumSegmentCount

The minimum number of segments by which a large TCP packet must be divisible before the transport can offload it to the hardware for segmentation.

[_In_] EvtAdapterOffloadSetGso

A pointer to the client driver's implementation of the EVT_NET_ADAPTER_OFFLOAD_SET_GSO callback function.

Return value

None

Remarks

The client driver calls NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES_INIT to initialize a NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES structure. The driver passes the initialized NET_ADAPTER_OFFLOAD_GSO_CAPABILITIES structure as a parameter to the NetAdapterOffloadSetGsoCapabilities function to register it.
