Description James Carter 2023-06-23 21:45:27 UTC 
This is for wicked-0.6.73-1.1.x86_64 upgraded 2023-06-21.

Years ago a Wicked man page recommended that in 
/etc/sysconfig/network/ifcfg-$INTERFACE if you have BOOTPROTO='dhcp',
in some use cases including mine you can save yourself troubleshooting
tangles if you also specify a fallback IP address.  Here's one of my
interface configurations: (Same symptom on non-bridge interfaces too.)

STARTMODE='auto'
BOOTPROTO='dhcp'
USERCONTROL='no'
# IPADDR='192.9.200.203/26'
# IPADDR_0='2600:3c01:e000:306::cb/112'
LLADDR='52:54:00:09:c8:cb'
BRIDGE='yes'
BRIDGE_PORTS='en0 vnet0'
BRIDGE_STP='off'

But after the recent update to Wicked, it syslogs 2 to 4 times/second:

    wickedd[898]: br0: address 192.9.200.203 covered by a static lease

(Nothing about IPv6, which on my net is normally gotten by DHCP, not 
RFC 4862 auto-configuration.)  Commenting out the fallback IPs fixed 
the problem.

The fallback IP has saved me several times from a "visit every machine"
scenario, and I would really like to see it usable again.  But if that
is not possible, at least the responsible Wicked component should not
get diarrhea of the log file when a violation is detected.

Wicked still support fallback IP addresses!

It looks like it is hitting the same regression as in bsc#1212806 .

The fix is in `wicked-0.6.73-2.1.x86_64` so it should work with simply tumbleweed update, sorry for the circumstances.
