** Description changed:
When trying to add another interface for a QETH device on a s390x system
netplan apply fails:
sudo netplan apply
Cannot replug encc003: [Errno 19] No such device

- even if a prior test with 'netplan --debug generate' seemed to pass:
+ It seems like rebinding of qeth devices is not allowed.
+ With qeth devices, I guess one needs to "offline & online" them...
+ Or like unbind a whole group of them, as there are three of them per
interface.

- After this failure the QETH device is no longer online, but was online

- However, after a reboot everything is fine and the interface up and
- running.

- Detailed steps (also to reproduce) are attached as well as the syslog.
- System is left as it is and can be used for further testing ...
- (contact 'jfh' on IRC)
+ However rebinding like that does not work.
+
+ Either qeth devices should be skipped, or one should operate on the
+ whole group of them, simulating chzdev -d c006; chzdev -e c006 -> or
+ just calling that.
+
+ Note that the device id to pass to chzdev is the whever device symlink
+ points to, e.g. 0.0.c006 in this case:
+
+ $ ls -latr /sys/class/net/encc006/device
+ lrwxrwxrwx 1 root root 0 Mar 16 13:55 /sys/class/net/encc006/device ->
