This seems to be hardly wicked related problem (wicked only applies
existing configuration to existing or hotplugging devices).
Do you mean that NIC interface is not present in your system? Is driver
loaded?
You could also check what is happening in dracut. To do so, you could
specify "rd.debug" parameter on the kernel command line to get dracut
logs.

Here is in short what we recommend to do, to get all wicked logs:

1) set DEBUG=all in /etc/sysconfig/network/config
2) systemctl restart wickedd
3) wicked --debug all ifup all  # systemctl restart wicked
4) wicked ifstatus all > status.log
5) wicked show-config > configs.log
6) journalctl -b -o short-iso > wicked.log
7) ip addr show > ip_addr.log
8) ip route show > routes.log
9) ip -6 route show >> routes.log

In general wicked debugging options are:
1) Command line
  - wicked --debug <all | help | ...>
    Enables debug level and sets filters by wicked facilities, e.g.:
    "all,-events,-socket,-objectmodel,-xpath,-xml,-dbus"
  - wicked --log-level <error | warning | notice | info | debug |
    debug1 | debug2 | debug3>
  - wicked --log-target <stderr | syslog>

2) Global
  - /etc/sysconfig/network/config
     - WICKED_DEBUG=most
        same to –debug option, applied to all services
     - WICKED_LOG_LEVEL=”debug2”
        same to –log-level, applied to all services
     - DEBUG=<yes|no|all|...>
        Compatibility fallback for WICKED_DEBUG, maps “yes” to “most”

Useful hints for logging:
- journalctl: journalctl -b -o short-iso > wicked.log
- rsyslog:

# /etc/rsyslog.d/wicked.conf
if      ($programname startswith 'wicked') \
then    -/var/log/wicked.log
&       ~
