If not, we can go from there and evaluate this much larger patch series. But let's try the simple thing first.
At high packet rates (say 30K pkt/s and more), we can still saturate the CPU. This is also mentioned in the announcement with claim that switch to rbtree based queue would be necessary to fully address that. My tests seem to confirm that but I'm still not sure it is worth backporting something as intrusive into stable 4.4.
No, it is not. If you worry about those things, you should not be running a 4.4 kernel, use 4.14 or newer please.
