=========================================================
+* **Updated the EAL Pseudo-random Number Generator.**
+
+ The lrand48()-based rte_rand() function is replaced with a
+ DPDK-native combined Linear Feedback Shift Register (LFSR)
+ pseudo-random number generator (PRNG).
+
+ This new PRNG implementation is multi-thread safe, provides
+ higher-quality pseudo-random numbers (including full 64 bit
+ support) and improved performance.
+
+ In addition, <rte_random.h> is extended with a new function
+ rte_rand_max() which supplies unbiased, bounded pseudo-random
+ numbers.
