Yeah, it's very much stateful, and tied closely to both TCP and the MAC
layer. So it has all the usual middlebox issues as far as that is
concerned... Also, APs need to transfer state between each other when
the client roams.
It does increase single-flow TCP throughput by up to a factor of two,
though... Which everyone knows is the most important benchmark number ;)
