David, The answer to your spec (UEFI 2.5) question is in: 2.6.2 Platform-Specific Elements 7. If a platform supports UEFI general purpose network applications, then the EFI_MANAGED_NETWORK_PROTOCOL, EFI_MANAGED_NETWORK_SERVICE_BINDING_PROTOCOL, EFI_ARP_PROTOCOL, EFI_ARP_SERVICE_BINDING_PROTOCOL, EFI_DHCP4_PROTOCOL, EFI_DHCP4_SERVICE_BINDING_PROTOCOL, EFI_TCP4_PROTOCOL, EFI_TCP4_SERVICE_BINDING_PROTOCOL, EFI_IP4_SERVICE_BINDING_PROTOCOL, EFI_IP4_CONFIG2_PROTOCOL, EFI_UDP4_PROTOCOL, and EFI_UDP4_SERVICE_BINDING_PROTOCOL are required. If additional IPv6 support is needed for the platform, then EFI_DHCP6_PROTOCOL, EFI_DHCP6_SERVICE_BINDING_PROTOCOL, EFI_TCP6_PROTOCOL, EFI_TCP6_SERVICE_BINDING_PROTOCOL, EFI_IP6_SERVICE_BINDING_PROTOCOL, EFI_IP6_CONFIG_PROTOCOL, EFI_UDP6_PROTOCOL, and EFI_UDP6_SERVICE_BINDING_PROTOCOL are additionally required. If the network application requires DNS capability, EFI_DNS4_SERVICE_BINDING_PROTOCOL and EFI_DNS4_PROTOCOL are required for the IPv4 stack. EFI_DNS6_SERVICE_BINDING_PROTOCOL and EFI_DNS6_PROTOCOL are required for the IPv6 stack. If the netw ork environment requires TLS features, EFI_TLS_SERVICE_BINDING_PROTOCOL,EFI_TLS_PROTOCOL and EFI_TLS_CONFIGURATION_PROTOCOL are required. If the network environment requires VLAN features, EFI_VLAN_CONFIG_PROTOCOL is required.
