[Cake] inbound cake or fq_codel shaping fails on cable on netflix reno

[Arie]

Two more data points. Shaped my connection to 250Mbit out of the advertised
250Mbit (my usual setting) and shaped to 200Mbit out of the 250Mbit. This
is a pre-linux-net-next cake running on an Edgemax ER4 with
kernel 3.10.107-UBNT.

The regular spikes in ICMP ping is due to the crappy Puma 6 chipset in the
cable modem. UDP is not affected.
