Now that SFB is kernel bound, and CHOKe as well, I've merged up support for CHOKe and SFB into this git repo for iproute2 and the tc traffic control tool. See: https://github.com/dtaht/iproute2bufferbloat There is a debloat-testing Linux kernel repo up at: http://git.infradead.org/debloat-testing.git It builds, I haven't booted into it yet. The patch set is pretty minor, if you already have a Linux-2.6 tree it pays to use: git clone --references your_existing_tree git://git.infradead.org/debloat-= testing.git (Doesn't have SFB yet, either.
