From 92c806838a6b0bf459c2ed61fe5d634998a2fa4e Mon Sep 17 00:00:00 2001 From: Greg Rose Date: Fri, 10 Jul 2015 19:36:03 -0400 Subject: [PATCH] i40e: Fix comment for ethtool diagnostic link test Orabug: 21764569 The existing comment is incorrect. Add new comment to point out that the PF reset does not affect link but if the reset is changed to a different type that does affect link then the link test would need to be moved to before the reset.
