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.

Typo fixed, thanks.

The rest is just from the commit message. There's a bit more in the patch itself, but it still doesn't just jump out at relatively slow people (like your editor...)
