NET_ADAPTER_OFFLOAD_CHECKSUM_CAPABILITIES_INIT function

Description

[!NOTE] The NET_ADAPTER_OFFLOAD_CHECKSUM_CAPABILITIES_INIT function is deprecated in NetAdapterCx 2.1 and later. For more information on current checksum offload functions, see Checksum offload.

The NET_ADAPTER_OFFLOAD_CHECKSUM_CAPABILITIES_INIT function initializes a NET_ADAPTER_OFFLOAD_CHECKSUM_CAPABILITIES structure.

Parameters

ChecksumCapabilities [_Out_]

A pointer to a driver-allocated NET_ADAPTER_OFFLOAD_CHECKSUM_CAPABILITIES structure.

IPv4 [_In_]

A flag specifying whether the hardware can calculate and validate IPv4 checksum.

Tcp [_In_]

A flag specifying whether the hardware can calculate and validate TCP checksum.

Udp [_In_]

A flag specifying whether the hardware can calculate and validate UDP checksum.

EvtAdapterOffloadSetChecksum [_In_]

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

Remarks

The NET_ADAPTER_OFFLOAD_CHECKSUM_CAPABILITIES structure initialized by this function is passed as a parameter to the NetAdapterOffloadSetChecksumCapabilities function.
