Subject: [PATCH net-next 0/7] ynl: add ignore-index flag for indexed-array

This patchset adds a way to mark if an indedex array is just an
array, and the index is uninteresting, as previously discussed[1].

Which is the case in most of the indexed-arrays in the current specs.

As the name indexed-array kinda implies that the index is interesting,
then I am using `ignore-index` to mark if the index is unused.

This adds some noise to YNL, and as it's only few indexed-arrays which
actually use the index, then if we can come up with some good naming,
it may be better to reverse it so it's the default behaviour.
