Subject: i40e: fix incorrect ethtool statistics veb and veb.tc_
Patch-mainline: v5.4-rc1
Git-commit: f21fa0606c383e8c7289ad89b4a610b441707d08
References: jsc#SLE-8025
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.
