Ip4Dxe implements the IPv4 protocol driver for the AMI UEFI network stack, producing EFI_IP4_SERVICE_BINDING_PROTOCOL, EFI_IP4_PROTOCOL, and EFI_IP4_CONFIG2_PROTOCOL. It handles IP packet input and output, reassembly and fragmentation, route table management, ARP-mediated interface management, and ICMP error generation. The driver consumes the Managed Network Protocol for underlying MNP frame transmit/receive and supports HII-based configuration via the Config2 NVRAM interface.
