@insomniacslk @pmazzini @hugelgupf Could you help review this pr? Moreover, are the unit tests mandatory? It seems hard to add the unit tests for the arp request in this testing environment. |

If the network manager in the operating system uses DHCP to obtain an IP for the network card, it will occupy the DHCP client port. In this case the release function will fail because the unicast connection with UDP socket needs the same port. Use a raw udp socket instead of a datagram udp socket to solve it.
