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.

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:

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 -> ../../../0.0.c006 |
[Impact]
Server users on s390x configuring qeth devices.
[Test case]
1) Reconfigure an interface for a QETH device
2) Verify that 'netplan apply' completes successfully, without error.
[Regression potential]
This change has minimal potential for regression, and it only skip qeth-based devices from "replugging", which "disconnects" them by unbinding and rebinding the driver. Potential issues would be limited to failure to rename interfaces without a reboot, for configurations that depend on this (but it already would not have worked due to netplan apply failing to rebind the device).
---
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
Traceback (most recent call last):

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.
