The systemd-networkd debug log (inside armhf container) reveals an interesting error message: "NDISC: Unexpected error while reading from ICMPv6, ignoring: Exchange full"

Reproducer: * Setup an armhf container, e.g. via: autopkgtest systemd --test-name=networkd-test.py --shell -U --apt-pocket=proposed=src:systemd,src:glibc -s -- lxd autopkgtest/ubuntu/impish/armhf * It will fail and drop you into the shell * cd test/ && apt install python3-nose * nosetests3 -v -s -m "test_.*_dhcp_ip6" networkd-test.py This is unrelated to the recent dnsmasq changes (LP: #1894619), as that would fail on all architectures, not just armhf. It still passes inside an amd64 LXD container, so it is also not related to armhf being tested inside a container. But it shows the difference between armhf vs amd64 container, that on armhf we're missing the DHCPSOLICIT (and therefore DHCPREPLY) messages, as can be seen from the dnsmasq log: dnsmasq-dhcp[]: DHCPSOLICIT(router_eth42) 00:02:00:00:ab:11:57:1e:20:2f:9e:56:5f:34 dnsmasq-dhcp[]: DHCPREPLY(router_eth42) 2600::1f 00:02:00:00:ab:11:57:1e:20:2f:9e:56:5f:34 autopkgtest-lxd-rtypaf The issue is most probably the same that causes the currently failing netplan.io/ethernets autopkgtest on armhf, if tested against glibc 2.34-0ubuntu1.
