From 890c402c7b113137c485367d5651f09a39c7d893 Mon Sep 17 00:00:00 2001 From: Ciara Loftus Date: Tue, 23 Jun 2020 13:06:56 +0000 Subject: [PATCH] i40e: add XDP ring statistics to dump VSI debug output Prior to this, only the Rx and Tx ring statistics were dumped. The XDP ring statistics are now dumped as well.
