If any other agent wishes to call Start() it must also follow these calling restrictions.

Parameters

This	Protocol instance pointer.
ControllerHandle	Handle of device to bind driver to
RemainingDevicePath	Optional parameter use to pick a specific child device to start.

Return values

EFI_SUCCESS Always succeeds.

		IN EFI_HANDLE	ControllerHandle,
		IN UINTN	NumberOfChildren,
		IN EFI_HANDLE *	ChildHandleBuffer
	)

Stop this driver on ControllerHandle. This service is called by the EFI boot service DisconnectController(). In order to make drivers as small as possible, there are a few calling restrictions for this service. DisconnectController() must follow these calling restrictions. If any other agent wishes to call Stop() it must also follow these calling restrictions.

Parameters

This	Protocol instance pointer.
ControllerHandle	Handle of device to stop driver on
NumberOfChildren	Number of Handles in ChildHandleBuffer. If number of children is zero stop the entire bus driver.

		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath	OPTIONAL
	)

Test to see if this driver supports ControllerHandle. This service is called by the EFI boot service ConnectController(). In order to make drivers as small as possible, there are a few calling restrictions for this service. ConnectController() must follow these calling restrictions. If any other agent wishes to call Supported() it must also follow these calling restrictions.

Parameters

◆ EmuSnpGetStatus()

EFI_STATUS EFIAPI EmuSnpGetStatus	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		OUT UINT32 *	InterruptStatus,
		OUT VOID **	TxBuffer
	)

Reads the current interrupt status and recycled transmit buffer status from a network interface.

Parameters

This	Protocol instance pointer.
InterruptStatus	A pointer to the bit mask of the currently active interrupts If this is NULL, the interrupt status will not be read from the device. If this is not NULL, the interrupt status will be read from the device. When the interrupt status is read, it will also be cleared. Clearing the transmit interrupt does not empty the recycled transmit buffer array.
TxBuffer	Recycled transmit buffer address. The network interface will not transmit if its internal recycled transmit buffer array is full. Reading the transmit buffer does not clear the transmit interrupt. If this is NULL, then the transmit buffer status will not be read. If there are no transmit buffers to recycle and TxBuf is not NULL, * TxBuf will be set to NULL.

Return values

EFI_SUCCESS Always succeeds.

Parameters

This	Protocol instance pointer.
