From 2d71e6334820deb82509458bcc52a33ef8b98083 Mon Sep 17 00:00:00 2001 From: Helin Zhang Date: Thu, 30 Apr 2015 23:03:18 +0800 Subject: [PATCH] i40e/base: fix error handling of NVM state update The state transitions after an error were not managed well, so these changes get us back to the INIT state or don't transit out of the INIT state after most errors.
