FYI: /etc/sysconfig/network-scripts/ has ifcfg-enccw0.0.1000 and
ifcfg-enccw0.0.e000; only difference between non-working network startup and
working network startup is in cio_ignore list in zipl.conf:
parameters="root=/dev/disk/by-path/ccw-0.0.0200-part1 rd.dasd=0.0.0200
rd.dasd=0.0.0100(diag) cio_ignore=all,!0009,!1000-1002,!e000-e002

hmm, unblocking of the devices must happen automagically, the script
responsible for that reads the /etc/sysconfig/network-scripts/ifcfg-*
files early during boot. What's the output of "systemctl status
device_cio_free"?
