I did a quick check on another s390x LPAR instance which is running
with Ubuntu 23.04 (6.1.0-16-generic) iproute2-6.1.0, there is still no
"flavour" attribute.
$ devlink port show
pci/0001:00:00.0/1: type eth netdev ens301
pci/0001:00:00.0/2: type eth netdev ens301d1
pci/0002:00:00.0/1: type eth netdev ens317
pci/0002:00:00.0/2: type eth netdev ens317d1
The behaviour didn't change with iproute2 built from source [1]
