In the absence of IMQ, this is what is recommended. Use ingress police to cap
overall incoming bandwidth and use qdiscs on LAN interface to shape traffic.
However, in cases like ISPs and a few corporate scenarios, the requirement is
to throttle/manage bandwith for incoming and outgoing traffic e.g. 64kbps incoming+outgoing
for an IP. In your scenarion, incoming and outgoing are capped/managed separately
but they cannot borrow from each other as they are on different interfaces.
IMQ being a single interface for both incoming and outgoing allows this.
