So valid_links would be fine, but we have links/link naming differences?
That's unfortunate. But now that I think about it, also it's array of
pointers in vif and array of structs in wdev?

We already have for_each_vif_active_link() so maybe add
for_each_vif_valid_link()? Though honestly in this case you could as
