It is unclear how to reproduce the issue.
So far, I always have multiple VLANs configured and accessible. The only
time I see errors similar to the ones from the reporter, is when the
same vlan with the same name is configured multiple times in a row
(which is an input/configuration error)
This bug will autoclose, unless better details are provided about the
initial state of the machine / cards, current and prior VLAN
configuration attempts. So far I cannot detect invalid behaviour, and
the only errors that are produced are correct (i.e. when attempting to
create a duplicate interface name)

Title:
Unable to configure VLAN on an additional OSA interface
Status in Ubuntu on IBM z Systems:

Status in iproute2 package in Ubuntu:

Status in linux package in Ubuntu:
Incomplete
Bug description:
After installing a base Ubuntu 18.04.1 server, an additional OSA device
"e530" is attached and configured with chzdev. Then a VLAN configuration should
be applied using the ip command.
However this results in the error message "RTNETLINK answers: File exists".
>----snip----
ip link add link ence530 name ence530.209 type vlan id 209
RTNETLINK answers: File exists
----snip----<
Executing the same steps on an Ubuntu 16.04.5 server, the ip command
finishes without an error message but the VLAN interface is also not
configured.
Reproduction:
- Install a 18.04.1 server
- attach an additional OSA interface
- configure a VLAN using the ip command
