Function Documentation

VirtioNetNvData()

EFI_STATUS EFIAPI VirtioNetNvData	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN BOOLEAN	ReadWrite,
		IN UINTN	Offset,
		IN UINTN	BufferSize,
		IN OUT VOID *	Buffer
	)

Performs read and write operations on the NVRAM device attached to a network interface.

Parameters

This	The protocol instance pointer.
ReadWrite	TRUE for read operations, FALSE for write operations.
Offset	Byte offset in the NVRAM device at which to start the read or write operation. This must be a multiple of NvRamAccessSize and less than NvRamSize.
BufferSize	The number of bytes to read or write from the NVRAM device. This must also be a multiple of NvramAccessSize.
Buffer	A pointer to the data buffer.

Return values

EFI_SUCCESS	The NVRAM access was performed.
EFI_NOT_STARTED	The network interface has not been started.
EFI_INVALID_PARAMETER	One or more of the parameters has an unsupported value.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
EFI_UNSUPPORTED	This function is not supported by the network interface.

VirtioNetReset()

EFI_STATUS EFIAPI VirtioNetReset	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN BOOLEAN	ExtendedVerification
	)

Resets a network adapter and re-initializes it with the parameters that were provided in the previous call to Initialize().

Parameters

This	The protocol instance pointer.
ExtendedVerification	Indicates that the driver may perform a more exhaustive verification operation of the device during reset.

Return values

EFI_SUCCESS	The network interface was reset.
EFI_NOT_STARTED	The network interface has not been started.
EFI_INVALID_PARAMETER	One or more of the parameters has an unsupported value.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
EFI_UNSUPPORTED	This function is not supported by the network interface.

VirtioNetStationAddress()

EFI_STATUS EFIAPI VirtioNetStationAddress	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN BOOLEAN	Reset,
		IN EFI_MAC_ADDRESS *New	OPTIONAL
	)

Modifies or resets the current station address, if supported.

Parameters

This	The protocol instance pointer.
Reset	Flag used to reset the station address to the network interfaces permanent address.
New	The new station address to be used for the network interface.

Return values

EFI_SUCCESS	The network interfaces station address was updated.
EFI_NOT_STARTED	The network interface has not been started.
EFI_INVALID_PARAMETER	One or more of the parameters has an unsupported value.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
EFI_UNSUPPORTED	This function is not supported by the network interface.

VirtioNetStatistics()

EFI_STATUS EFIAPI VirtioNetStatistics	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN BOOLEAN	Reset,
		IN OUT UINTN *StatisticsSize	OPTIONAL,
		OUT EFI_NETWORK_STATISTICS *StatisticsTable	OPTIONAL
	)

Resets or collects the statistics on a network interface.

Parameters

This	Protocol instance pointer.
Reset	Set to TRUE to reset the statistics for the network interface.
StatisticsSize	On input the size, in bytes, of StatisticsTable. On output the size, in bytes, of the resulting table of statistics.
StatisticsTable	A pointer to the EFI_NETWORK_STATISTICS structure that contains the statistics.

Return values

EFI_SUCCESS	The statistics were collected from the network interface.
EFI_NOT_STARTED	The network interface has not been started.
EFI_BUFFER_TOO_SMALL	The Statistics buffer was too small. The current buffer size needed to hold the statistics is returned in StatisticsSize.
EFI_INVALID_PARAMETER	One or more of the parameters has an unsupported value.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
EFI_UNSUPPORTED	This function is not supported by the network interface.
