Routine Description:

    This returns information about children to be enumerated by a multifunction
    driver.

Arguments:

    Channel - Channel to try and set to F-Type DMA

    ChannelInfo - Result of the set. Returns the mask of channels set to F-Type

Return Value:

    Status code that indicates whether or not the function was successful.
