IOCTL_STORAGE_FIRMWARE_DOWNLOAD IOCTL (ntddstor.h)
A driver can use IOCTL_STORAGE_FIRMWARE_DOWNLOAD to download a firmware image to a storage device, but does not activate it. If the image to be downloaded is larger than the controller’s maximum data transfer size, this IOCTL will have to be called multiple times until the entire image is downloaded.

Irp->AssociatedIrp.SystemBuffer contains STORAGE_HW_FIRMWARE_DOWNLOAD data that specifies information about the downloaded firmware to activate.Input buffer length
Parameters.DeviceIoControl.InputBufferLength indicates the size, in bytes, of the parameter buffer at Irp->AssociatedIrp.SystemBuffer, which must be >= sizeof(STORAGE_HW_FIRMWARE_DOWNLOAD).Output buffer
This IOCTL has no output structure.
