I'm not able to reach full speed with bond + HTB + sfq on 2.6.29.1, both
with and without these patches. I seem to get a lot of drops on sfq
qdiscs, whatever quantum I set. Playing with IRQ affinity doesn't help.
I didn't check without bond.

With bond + HFSC + sfq, I'm able to reach the speed. It doesn't seem to
overspill with 580 mbps load. Jarek, would your patches help with HSFC
overspill ? I will check tomorrow under 750 mbps load. 

# ethtool -k eth0
Offload parameters for eth0:
