IScsiDhcp6ParseReply()

EFI_STATUS EFIAPI IScsiDhcp6ParseReply	(	IN EFI_DHCP6_PROTOCOL *	This,
		IN VOID *	Context,
		IN EFI_DHCP6_PACKET *	Packet
	)

EFI_DHCP6_INFO_CALLBACK is provided by the consumer of the EFI DHCPv6 Protocol instance to intercept events that occurs in the DHCPv6 Information Request exchange process.

Parameters

[in]	This	Pointer to the EFI_DHCP6_PROTOCOL instance that is used to configure this callback function.
[in]	Context	Pointer to the context that is initialized in the EFI_DHCP6_PROTOCOL.InfoRequest().
[in]	Packet	Pointer to Reply packet that has been received. The EFI DHCPv6 Protocol instance is responsible for freeing the buffer.

Return values

EFI_SUCCESS	Tell the EFI DHCPv6 Protocol instance to finish Information Request exchange process.
EFI_NOT_READY	Tell the EFI DHCPv6 Protocol instance to continue Information Request exchange process.
EFI_ABORTED	Tell the EFI DHCPv6 Protocol instance to abort the Information Request exchange process.
EFI_UNSUPPORTED	Tell the EFI DHCPv6 Protocol instance to finish the Information Request exchange process because some request information are not received.
