The IoSetStartIoAttributes routine sets attributes for the driver's StartIo routine.
DeviceObject [in]Pointer to the device object for the driver's device.
DeferredStartIo [in]If TRUE, the I/O manager will defer any call to the driver's StartIo routine while the driver is already inside the routine. In particular, if the StartIo routine calls IoStartNextPacket, the StartIo routine will not be called again until the current invocation completes. The default is FALSE.
NonCancelable [in]If TRUE, the IRP cannot be canceled once it has been dequeued by a call to IoStartNextPacket. The default is FALSE. Drivers that set this member to FALSE must synchronize their IRP handling with the cancel spin lock.
