I really think that can be done more easily though. For one, clearly we
already have the warning, so we don't need more infrastructure to catch
such errors?! Also, this may end up hiding issues that we don't yet
understand, like the nullfunc one you were talking about. The delBA one
we now understand fully, so it makes more sense to simply suppress
sending delBA when we are going to disassociate by way of associating
with a new AP, no?
