A pointer to a UCMTCPCI_PORT_CONTROLLER_SET_TRANSMIT_IN_PARAMS structure that contains the value to set in the TRANSMIT Register. To get the structure, call WdfRequestRetrieveInputBuffer by passing the received framework request object. This structure is declared in UcmTcpciSpec.h.
Input buffer length
The size of the UCMTCPCI_PORT_CONTROLLER_SET_TRANSMIT_IN_PARAMS structure.
Status block
