From: Vishnu Singh <[email protected]> Added LinkLocalAddressing=ipv4 to the network configuration to enable automatic IPv4 address self-configuration (169.254.x.x/16) when no DHCP server is available on the network. This configuration applies to all physical Ethernet interfaces (eth*) and USB Ethernet adapters (usb*). This change: - Allows devices to communicate on local networks without manual IP configuration - Ensures addresses are assigned directly to the physical interfaces (not virtual interfaces) - Maintains network connectivity in zero-configuration environments - Follows the RFC 3927 standard for IPv4 Link-Local addressing - Provides consistent behavior across all Ethernet connections, including USB adapters The Link-Local addressing serves as a fallback mechanism, enabling basic network functionality and service discovery even in the absence of network infrastructure.
