Thanks for the feedback. That's interesting. What are you using for your tests
(wget, ...)?

Can you give a pre-3.11.7 kernel a try if you find the time? I started
working on RN102 during 3.10-rc cycle but do not remember if I did the
first preformance tests on 3.10 or 3.11. And if you find more time,
3.11.7 would be nice too ;-)

Cheers,
