From 4443ec94d246e65fcee8ebf63f4d3abea0ff86df Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Thu, 13 Nov 2014 08:23:12 +0000 Subject: [PATCH] i40e: clear NVM update state on ethtool test Once in a great while the NVMUpdate tools and the driver get out of phase with each other. This gives us a way to reset things without having to unload the driver.
