Is it possible to modify hostapd for the purpose of sharping buffered frames in 802.11 power saving mode?

Thanks Jouni, now I am more clear about the hostapd.

I am new to kernel/driver field, but will try if this way is possible.
Could you please answer me that can my goal be achieved if I get a prism
