PxeInit()

EFI_STATUS PxeInit	(	SNP_DRIVER *	Snp,
		UINT16	CableDetectFlag
	)

Call UNDI to initialize the interface.

Parameters

Snp	Pointer to snp driver structure.
CableDetectFlag	Do/don't detect the cable (depending on what undi supports).

Return values

EFI_SUCCESS	UNDI is initialized successfully.
EFI_DEVICE_ERROR	UNDI could not be initialized.
Other	Other errors as indicated.

SnpUndi32Initialize()

EFI_STATUS EFIAPI SnpUndi32Initialize	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN UINTN ExtraRxBufferSize	OPTIONAL,
		IN UINTN ExtraTxBufferSize	OPTIONAL
	)

Resets a network adapter and allocates the transmit and receive buffers required by the network interface; optionally, also requests allocation of additional transmit and receive buffers.

This function allocates the transmit and receive buffers required by the network interface. If this allocation fails, then EFI_OUT_OF_RESOURCES is returned. If the allocation succeeds and the network interface is successfully initialized, then EFI_SUCCESS will be returned.

Parameters

This	A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
ExtraRxBufferSize	The size, in bytes, of the extra receive buffer space that the driver should allocate for the network interface. Some network interfaces will not be able to use the extra buffer, and the caller will not know if it is actually being used.
ExtraTxBufferSize	The size, in bytes, of the extra transmit buffer space that the driver should allocate for the network interface. Some network interfaces will not be able to use the extra buffer, and the caller will not know if it is actually being used.

Return values

EFI_SUCCESS	The network interface was initialized.
EFI_NOT_STARTED	The network interface has not been started.
EFI_OUT_OF_RESOURCES	There was not enough memory for the transmit and receive buffers.
EFI_INVALID_PARAMETER	This parameter was NULL or did not point to a valid EFI_SIMPLE_NETWORK_PROTOCOL structure.
EFI_DEVICE_ERROR	The command could not be sent to the network interface.
EFI_UNSUPPORTED	The increased buffer size feature is not supported.
