Hi,
A reminder. I pushed the first version to the community in September.
All most 4 mouths passed. I'm wondering if we can speed up a little bit. :)
Thanks,
Chris

This patch set adds offload support for sFlow.
Psample is a genetlink channel for packet sampling. TC action act_sample
uses psample to send sampled packets to userspace.
When offloading sample action to TC, userspace creates a unique ID to
map sFlow action and tunnel info and passes this ID to kernel instead
of the sFlow info. psample will send this ID and sampled packet to
userspace. Using the ID, userspace can recover the sFlow info and send
sampled packet to the right sFlow monitoring host.
