Subject: [Intel-wired-lan] [next PATCH S7 1/9] i40e: fix incorrect ethtool statistics veb and veb.tc_
Date: Tue,  2 Jul 2019 08:22:51 -0400	[thread overview]
Message-ID: <20190702122259.79070-1-alice.michael@intel.com> (raw)

From: Dmitrii Golovanov <dmitrii.golovanov@intel.com>

This patch fixes missing call of i40e_update_veb_stats() in function
i40e_get_ethtool_stats() to update stats data of VEB and VEB TC
counters before they are written into ethtool buffer.
Before the patch ethtool counters may fell behind interface counters.
