Public bug reported:
After suspending and resuming my desktop, my tablet could not resolve
its hostname over mDNS. `getent hosts daniel-desktop3.local` has no
output. Wireshark on the desktop captured incoming mDNS packets but no
outgoing response. Disconnecting/reconnecting the desktop's ethernet in
NetworkManager generated log output but wasn't a fix. `systemctl restart
avahi-daemon.service` worked around the problem.
