From 49d358e0e746dc24bfb1b1cf98c17064e5177424 Mon Sep 17 00:00:00 2001 From: Marta Plantykow Date: Fri, 15 May 2020 17:42:16 -0700 Subject: [PATCH] ice: Add XDP Tx to VSI ring stats When XDP Tx program is loaded and packets are sent from interface, VSI statistics are not updated. This patch adds packets sent on Tx XDP ring to VSI ring stats.
