Routine Description:
This function is called by the operating system when the device is
started.
It is responsible for starting the miniports. This code is specific to
the adapter because it calls out miniports for functions that are specific
to the adapter.
Arguments:
DeviceObject - pointer to the driver object
Irp - pointer to the irp
ResourceList - pointer to the resource list assigned by PnP manager
Return Value:
NT status code.
