Function Documentation

PxeIp2Mac()

EFI_STATUS PxeIp2Mac	(	IN SNP_DRIVER *	Snp,
		IN BOOLEAN	IPv6,
		IN EFI_IP_ADDRESS *	IP,
		IN OUT EFI_MAC_ADDRESS *	MAC
	)

Call undi to convert an multicast IP address to a MAC address.

Parameters

Snp	Pointer to snp driver structure.
IPv6	Flag to indicate if this is an ipv6 address.
IP	Multicast IP address.
MAC	Pointer to hold the return MAC address.

Return values

EFI_SUCCESS	The multicast IP address was mapped to the multicast HW MAC address.
EFI_INVALID_PARAMETER	Invalid UNDI command.
EFI_UNSUPPORTED	Command is not supported by UNDI.
EFI_DEVICE_ERROR	Fail to execute UNDI command.

SnpUndi32McastIpToMac()

EFI_STATUS EFIAPI SnpUndi32McastIpToMac	(	IN EFI_SIMPLE_NETWORK_PROTOCOL *	This,
		IN BOOLEAN	IPv6,
		IN EFI_IP_ADDRESS *	IP,
		OUT EFI_MAC_ADDRESS *	MAC
	)

Converts a multicast IP address to a multicast HW MAC address.

This function converts a multicast IP address to a multicast HW MAC address for all packet transactions. If the mapping is accepted, then EFI_SUCCESS will be returned.

Parameters

This	A pointer to the EFI_SIMPLE_NETWORK_PROTOCOL instance.
IPv6	Set to TRUE if the multicast IP address is IPv6 [RFC 2460]. Set to FALSE if the multicast IP address is IPv4 [RFC 791].
IP	The multicast IP address that is to be converted to a multicast HW MAC address.
MAC	The multicast HW MAC address that is to be generated from IP.

Return values

EFI_SUCCESS	The multicast IP address was mapped to the multicast HW MAC address.
EFI_NOT_STARTED	The Simple Network Protocol interface has not been started by calling Start().
EFI_INVALID_PARAMETER	IP is NULL.
EFI_INVALID_PARAMETER	MAC is NULL.
EFI_INVALID_PARAMETER	IP does not point to a valid IPv4 or IPv6 multicast address.
EFI_DEVICE_ERROR	The Simple Network Protocol interface has not been initialized by calling Initialize().
EFI_UNSUPPORTED	IPv6 is TRUE and the implementation does not support IPv6 multicast to MAC address conversion.
