From 96a39aed25e6559b160786117df124084feb9080 Mon Sep 17 00:00:00 2001 From: Aaron Salter Date: Fri, 2 Dec 2016 12:33:02 -0800 Subject: [PATCH] i40e: Acquire NVM lock before reads on all devices Acquire NVM lock before reads on all devices. Previously, locks were only used for X722 and later. Fixes an issue where simultaneous X710 NVM accesses were interfering with each other.
