From 2d28bb5ddd0fb7c3bed44f3f3fbc7a7bc449ea7a Mon Sep 17 00:00:00 2001 From: Yipeng Wang Date: Fri, 26 Oct 2018 02:53:41 -0700 Subject: [PATCH] hash: remove unnecessary pause There is a rte_pause in hash table reset function. Since the loop is not a polling loop on shared data structure, the rte_pause is not needed.
