+  * This is a simple functional test for rte_smp_mb() implementation.
+  * I.E. make sure that LOAD and STORE operations that precede the
+  * rte_smp_mb() call are globally visible across the lcores
+  * before the the LOAD and STORE operations that follows it.
+  * The test uses simple implementation of Peterson's lock algorithm
+  * for two execution units to make sure that rte_smp_mb() prevents
+  * store-load reordering to happen.
+  * Also when executed on a single lcore could be used as a approxiamate
+  * estimation of number of cycles particular implementation of rte_smp_mb()
