It's not "Internet Functional Block", it's "Intermediate Functional Block", it has been described here:
It is by no means obscure for people who'd like to do ingress shaping.
Currently you can only do traffic shaping on egress, that means that if you have a router with 3 internal interfaces then each interface will be shaped separately, so each segment of the network can get a maximum of 1/3 of the available bandwidth, this sucks if there are two leechers on one net and none on the other.
With IFB (or IMQ previously) you can set up a virtual network device between your Internet line and the rest of the network so all the incoming traffic can be shaped together.
