[dpdk-dev] [PATCH] eal: fix TSC resolution in hz for ppc_64 architecture

From: Gowrishankar Muthukrishnan In ppc_64, rte_rdtsc() returns timebase register value which increments at independent timebase frequency and hence not related to lcore cpu frequency to derive into. In this patch, we fix get_tsc_freq() to not depend upon rte_rdtsc(), but obtain cpu current frequ
