TC classifiers/actions were converted to RCU by John in the series: http://thread.gmane.org/gmane.linux.network/329739/focus=329739 and many follow on patches. This is the last patch from that series that finally drops ingress spin_lock. Single cpu ingress+u32 performance goes from 22.9 Mpps to 24.5 Mpps. In two cpu case when both cores are receiving traffic on the same device and go into the same ingress+u32 the performance jumps from 4.5 + 4.5 Mpps to 23.5 + 23.5 Mpps Signed-off-by:
