NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES_INIT function (netadapter.h)

  • Article

The NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES_INIT function initializes a NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES structure.

Syntax

void NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES_INIT(
  [_Out_] NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES *Capabilities,
  [_In_]  NET_ADAPTER_OFFLOAD_LAYER3_FLAGS             Layer3Flags,
  [_In_]  PFN_NET_ADAPTER_OFFLOAD_SET_TX_CHECKSUM      EvtAdapterOffloadSetTxChecksum
);

Parameters

[_Out_] Capabilities

A pointer to a driver-allocated NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES structure.

[_In_] Layer3Flags

Flags specifying the layer 3 protocol variations that the NIC can successfully perform Tx checksum on.

[_In_] EvtAdapterOffloadSetTxChecksum

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

Return value

None

Remarks

The client driver calls NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES_INIT to initialize a NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES structure. The driver passes the initialized NET_ADAPTER_OFFLOAD_TX_CHECKSUM_CAPABILITIES structure as a parameter to the NetAdapterOffloadSetTxChecksumCapabilities function to register it.
