Hi Jesper,

(re-send after getting the right netdev ML address)

Following our LPC discussion on lock-free queue algorithms
for qdisc, here is some info on the wfcqueue implementation
found in Userspace RCU. See http://urcu.so for info and
git repository.

Here is the wfcqueue ported to the Linux kernel I sent last
year as RFC:
https://lkml.org/lkml/2013/3/14/289

I'm very interested to learn if it fits well for your
use-case,

Feedback is welcome,

Thanks!

Mathieu
