I installed iproute2-ss090115 with the new patch but the results are
the same for my test scenery. HTB keeps sending 620Mbit/s when I
configure it's ceil to 555Mbit/s, with 800 bytes packets long.

I'm working on this, don't worry. Since I have a traffic
generator/analyser, any modification you would make I can test it.
You're free to ask.

I've been looking inside htb source code. The granularity problem
could be in the use qdisc_rate_table or near that.
