[stork-users] How to set option-43 from stork gui

In fact, I think you have to add option 43 with suboption 1 and the 
binary value of "C0A8A9FE" (not 0104c0a8a9fe). If I understand 
correctly, the "01" is the suboption code and the 04 is the length of 
the payload. These two values are prepended to the suboption value when 
specifying suboption code of 1 and the binary value.

The reason why you're seeing this error when trying to specify the 
payload for the option 43 is that Stork assumes that the option 43 has 
option definition (which is empty) option with suboptions. That's why it 
uses csv-format set to true (instead of false), and Kea rejects it 
because there should be no payload when csv-format is true.
