I don't understand, please provide more details.
This is an ArrayNest, right?
[ARRAY-ATTR]
[ENTRY]
[MEMBER1]
[MEMBER2]
[ENTRY]
[MEMBER1]
[MEMBER2]
Which level are you saying doesn't matter?
If entry is a nest it must be a valid nest.
What the comment you're quoting is saying is that the nla_type of ENTRY
doesn't matter.
