[Bloat] Does VDSL interleaving+FEC help bufferbloat?

[Dave Taht]

dsl interleave was added primarily to make multicast udp tv streams
work better (as they are very intolerant of packet loss). Often (as in
free's implementation) these streams are "invisible" to the overlying
IP applications. It typically adds at least 6ms of delay to an already
slow technology.

Do measure unloaded latency with and without it on, it's been a long
time since I fiddled with it....
