[Make-wifi-fast] [Bloat] benefits of ack filtering

I'm skeptical that this would improve single stream throughput by a factor
of two. The larger RTT would drive larger aggregations and it's
aggregation that scales peak average throughput.
Also, the time difference between the 802.11 ack and the client network
stack writing the TCP ack would probably be in the 100s of microseconds
(mileage will vary.) So it's the client's media access that will drive the
increase in RTT. It might be preferred to modify EDCA parameters to
reduce media access latencies for TCP acks rather than spoof them.
