View the official Windows Driver Kit DDI referenceNo description available.
The NET_ADAPTER_OFFLOAD_RSC_CAPABILITIES structure describes a network interface card (NIC)'s capabilities for receive segment coalescence (RSC).
SizeThe size of this structure, in bytes.
Layer3FlagsFlags specifying the layer 3 protocols that the NIC can successfully perform RSC on. NetAdapterOffloadLayer3FlagIPv4NoOptions and NetAdapterOffloadLayer3FlagIPv6NoExtensions are the only valid values.
Layer4FlagsFlags specifying the layer 4 protocols that the NIC can successfully perform RSC on. NetAdapterOffloadLayer4FlagTcpNoOptions and NetAdapterOffloadLayer4FlagUdp are the only valid values. Layer 3 flags must be set if the NetAdapterOffloadLayer4FlagTcpNoOptions flag is set.
TcpTimestampOptionOptional. A flag specifying whether the hardware can perform RSC on packets with a timestamp.
EvtAdapterOffloadSetRscA pointer to the client driver's implementation of the EVT_NET_ADAPTER_OFFLOAD_SET_RSC callback function.
Call NET_ADAPTER_OFFLOAD_RSC_CAPABILITIES_INIT to initialize this structure. The client driver passes an initialized NET_ADAPTER_OFFLOAD_RSC_CAPABILITIES structure as a parameter to NetAdapterOffloadSetRscCapabilities.
To see an example of how a client driver might set up its RSC hardware offload capabilities, see Receive Segment Coalescing offload.
