From c420815d12b744ad8cf9312af13af794bad48216 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Tue, 3 May 2016 15:13:15 -0700 Subject: [PATCH] i40e: change Rx hang message into a WARN_ONCE Use WARN_ONCE in order to highlight the issue, but don't display a warning every time. The user should be able to see the ethtool counter we created if necessary to see how often it is occurring.
