hostapd listen interval = zero?

Question please:

I'm seeing something I described here:

In short: there's "traffic for you" beacons (TIM bit set), the client
wakes up, but no data is sent by the AP, and the client goes to sleep
again. I hoped this would maybe behave properly with your latest

Which piece of code is responsible for sending the buffered data after
a client wakes up? Would this be in hostapd or in the driver? Where to
look? I'm using the nl80211 driver.

Thank you,
