Looks/tested ok for me. Acked.

I've tested various setups in the series (adding/removining varios PMD 
configurations, isolating and distributing queueus, queue re-balancing). 
I also ran a number of scaling performance tests and did not see any 
impact on the performance side.

As I said in the previous patches, I'll wait until Ilya has time to test 
also as it's important that we don't see any regressions with this part 
of the codebase for the various usecases.

Thanks
Ian
