This required version is not true, please verify it properly, I'm not going to do it every time :).

Same wrong NM version as in the test.

Flags should be inserted to the map all the time.

Can be turned into an enum.

Can be turned into an enum.

Again not true.

I tried to get the version from here:

Is that incorrect?
If so, from where do I check the version?

From where can I get the possible values? Because I cannot find them here: https://developer.gnome.org/NetworkManager/stable/settings-macsec.html

That is probably incorrect, the easiest way how to search for this is to clone NetworkManager and checkout to a branch you want to check and grep the define you are looking for.

So for example in my cloned NM, I go to "nm-1-6" branch and do "grep -ir NM_SETTING_MACSEC_MODE" and see that this property is defined there. You should check all NM versions so if it's defined in NM 1.6, I test also whether it is in NM 1.4. I usually start checking from the middle, which means "nm-1-8" branch and go to newer or older based on the result.

You can get it when you clone NetworkManager and go to the header file where these properties are defined. In your case it is in libnm-core/nm-setting-macsec.h.

Isn't default validation 2, which means "strict" in your case.

mode() > Macsec::Psk

validation() != Macsec::Strict

In this case you don't need to define the defines above, just list both enums without assigned values, or you can just assign 0 to the first one to make sure it starts from 0.
