From 2eb34bafb352d2ddd02b184c73f3ec4706a4cc12 Mon Sep 17 00:00:00 2001 From: Tony Nguyen Date: Fri, 16 Mar 2018 15:34:06 -0700 Subject: [PATCH] ixgbevf: Add XDP queue stats reporting XDP stats are included in TX stats, however, they are not reported in TX queue stats since they are setup on different queues. Add reporting for XDP queue stats to provide consistency between the total stats and per queue stats.
