From a4aca79ba4d866627383efa5967a4540a67ccffa Mon Sep 17 00:00:00 2001 From: Harry van Haaren Date: Mon, 9 Nov 2015 10:22:22 +0000 Subject: [PATCH] i40e: fix stats reset This patch fixes a bug where only some of the statistics were being reset when calling rte_eth_stats_reset() or rte_eth_xstats_reset(). As both the stats reset and xstats reset do the same, refactor away the duplicated function. This patch marks the VSI to update its offset, causing the stats be look like they are reset.
