Excellent! I'm glad this is applied. I'm having trouble figuring out how it works, though. As a test, I'm trying to set up SFQ equivalent to ESFQ's "hash dst". Here's what I do, and this is what I get: ------------------------------------------------------------------------ # ./tc qdisc add dev eth0 root handle 1: sfq # ./tc filter add dev eth0 parent 1: flow hash keys dst RTNETLINK answers: Invalid argument We have an error talking to the kernel ------------------------------------------------------------------------ I've tried a few different keys with the same results. I don't know what I'm doing wrong, or even where to start figuring it out. Can you point me in the right direction? Here are some details that may be pertinent: - current net-2.6 git (I double-checked) - CONFIG_NET_CLS_FLOW=y - current iproute2 git - running on amd64 user-mode Linux Thanks, Corey
