Optimize queues and scheduling with a ring based implementation. Ring operations are not atomic and behind locks. Scheduler throughput improves in L2fwd test about 30%. Buffer header gets smaller and not related to burst size, which has positive impact to direct mode pktio throughput also. 2x10GE (Mpps) | direct | | atomic | cpus | before | after | speed up | before | after | speed up 1 | 19.4 | 19.8 | 1.02 | 13.1 | 15.0 | 1.14 2 | 29.7 | 29.7 | 1.00 | 16.9 | 21.5 | 1.27 4 | | 24.7 | 28.7 | 1.16
