Hi,
for testing I add a hotplug script. Bellow I did copy my test sequence and the
output. There are a few seconds between
the commands. If 'wifi ...' is called, the 2003: address of my wan interface is
gone. The other addresses are still
assigned. If 'ubus ...' is called, the wan interface gets the same 2003:
address back.
Regards,
Hartmut
