NDIS_SET_PACKET_TIME_TO_SEND sets the TimeToSend value in the out-of-band data block associated with a given packet descriptor.
VOID NDIS_SET_PACKET_TIME_TO_SEND( [in] PNDIS_PACKET Packet, [in] ULONGLONG TimeToSend );
Pointer to a packet descriptor allocated by the caller for a send.
Specifies the system time at which the packet should be transmitted over the network.
Protocols can use NDIS_SET_PACKET_TIME_TO_SEND to set this timestamp in the out-of-band data block associated with a driver-allocated packet descriptor to be passed in a subsequent call to NdisSendPackets or NdisSend. Setting the timestamp does not affect when the packet is actually transmitted; instead, the timestamp is used for recordkeeping. A protocol driver can use the timestamp to determined how long it takes to complete the sending of a paket.
All timestamps set in the NDIS_PACKET_OOB_DATA blocks associated with packet descriptors are expressed in system time units as the number of 100-nanosecond intervals since January 1, 1601.
A protocol can call NdisGetCurrentSystemTime and add some number of system time units to the returned value in order to supply the TimeToSend argument to NDIS_SET_PACKET_TIME_TO_SEND, unless the client that initiated the send request has already supplied such a timestamp.
