[dpdk-dev] [PATCH v3 1/3] eal: introduce integer divide through reciprocal

2017-09-03 Thread Pavan Nikhilesh

In some use cases of integer division, denominator remains constant and numerator varies. It is possible to optimize division for such specific scenarios. The librte_sched uses rte_reciprocal to optimize division so, moving it to eal/common would allow other libraries and applications to use it.
