Function Documentation

PxeGetStnAddr()

EFI_STATUS PxeGetStnAddr

(

SNP_DRIVER *

Snp

)

Call UNDI to read the MAC address of the NIC and update the mode structure with the address.

Parameters

Snp	Pointer to snp driver structure.

Return values

EFI_SUCCESS	The MAC address of the NIC is read successfully.
EFI_DEVICE_ERROR	Failed to read the MAC address of the NIC.

PxeSetStnAddr()

EFI_STATUS PxeSetStnAddr	(	SNP_DRIVER *	Snp,
		EFI_MAC_ADDRESS *	NewMacAddr
	)

Call UNDI to set a new MAC address for the NIC.

Parameters

Snp	Pointer to Snp driver structure.
NewMacAddr	Pointer to a MAC address to be set for the NIC, if this is NULL then this routine resets the mac address to the NIC's original address.

SnpUndi32StationAddress()

EFI_STATUS EFIAPI SnpUndi32StationAddress	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN BOOLEAN	Reset,
		IN EFI_MAC_ADDRESS *New	OPTIONAL
	)

Modifies or resets the current station address, if supported.

This function modifies or resets the current station address of a network interface, if supported. If Reset is TRUE, then the current station address is set to the network interface's permanent address. If Reset is FALSE, and the network interface allows its station address to be modified, then the current station address is changed to the address specified by New. If the network interface does not allow its station address to be modified, then EFI_INVALID_PARAMETER will be returned. If the station address is successfully updated on the network interface, EFI_SUCCESS will be returned. If the driver has not been initialized, EFI_DEVICE_ERROR will be returned.

Parameters

This	A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
Reset	Flag used to reset the station address to the network interface's permanent address.
New	New station address to be used for the network interface.

Return values

EFI_SUCCESS	The network interface's station address was updated.
EFI_NOT_STARTED	The Simple Network Protocol interface has not been started by calling Start().
EFI_INVALID_PARAMETER	The New station address was not accepted by the NIC.
EFI_INVALID_PARAMETER	Reset is FALSE and New is NULL.
EFI_DEVICE_ERROR	The Simple Network Protocol interface has not been initialized by calling Initialize().
EFI_DEVICE_ERROR	An error occurred attempting to set the new station address.
EFI_UNSUPPORTED	The NIC does not support changing the network interface's station address.
