Bufferbloat issue when using ipv4 and ipv6

[dennypage]

@RobbieTT I had suggested the experiment because on reading the description of your config at the time it seemed that you might not have a choke (buffer) point in your download path. And if there is no choke point, shaping such as CoDel is a hinderance rather than a benefit. Sounds like you were already aware of this however.
