Just wanted to follow up on the earlier reply and check if you've
had a chance to review it.
To explain the implementation a bit more clearly: The issue is that
response indication from a MAC perspective doesn't really make sense
elsewhere. It's simply embedded into the PPDU for the VIF that has
response indication configured, and the receiver uses it to determine
which type (if any) of ACK to respond with. So it's entirely handled
by the lower MAC besides of course setting the value from the upper MAC.

While it may seem more ideal to sit in a per station or something similar
where the lifetimes are more natural, there isn't a capability exchange
that occurs - configuration is more for local transmitter config. On the
receiver side, it isn't communicated to the upper MAC at all - so considering
it as a STA entry dosen't really make much sense.

Please let me know if you see any issues with this approach.
Looking forward to hear your thoughts on this whenever you have a chance
