I updated from 13.1 to 13.2.

In 13.1, the dsl connection was set up automatically. With 13.2, the support
for that is gone (as is the YaST DSL and ISDN module).

Searching Bugzilla and the web I found that one could use NetworkManager to set
up DSL, but this machine is used as a router with no one logged in normally, so
NetworkManager is not an option.

As the configuration (fortunately) was not changed by the update I could still
activate the DSL connection to the internet with the cinternet command. 

With an existing dsl0 interface, I can use wicked to bring it down:
wicked ifdown dsl0 works as expected.

However, wicked is not able to bring the interface up again:
wicked ifup dsl0 fails.

As a workaround, I created a /etc/systemd/system/dsl0.system unit file:

[Unit]
Description=Control the dsl connection
# iptables-rules runs some iptables script that for some reason delays the 
# execution of this service so it actually works
After=network-online.target iptables-rules.service
Wants=network-online.target iptables-rules.service

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/cinternet -i dsl0 -A
ExecStart=/usr/bin/cinternet -i dsl0 -D
ExecStart=/sbin/ip address show dev dsl0
ExecStop=/usr/bin/cinternet -i dsl0 -H
ExecStop=/usr/bin/cinternet -i dsl0 -O
KillMode=process
Restart=

[Install]
WantedBy=multi-user.target


But to me this looks more like a hack, especially I had to find some way to
convince systemd to actually run this so late during boot that the ethernet
interfaces are already set up, because otherwise it does not work during boot.
