[dpdk-dev] [PATCH v2 1/3] examples/l3fwd: reorganize code for better performance

Moved rfc1812 process prior to NEON registers store. On N1SDP, this reorganization mitigates CPU frontend stall and backend stall when forwarding. On N1SDP with MLX5 40G NIC, this change showed 10.2% performance gain in single port single core MRR test. On ThunderX2, this changed showed no perform
