[Cake] cake and hfsc rate limiters outperforming htb on one-armed router

For whatever reason, I’m seeing the rate limiters in cake and hfsc vastly outperform htb in the one-armed router configuration I described in my previous thread. To simplify things, I apply the qdiscs with a single class only at egress of eth0 on apu1a: apu2a <— default VLAN —> apu1a <—
