From 17413a80bcff78ceb371fb6a34d888780ad7b7fa Mon Sep 17 00:00:00 2001 From: Greg Rose <gregory.v.rose@intel.com> Date: Wed, 4 Jun 2014 01:23:13 +0000 Subject: [PATCH] i40e: Stop the VF device after setting its MAC address If the host VMM administrator has changed the VF device's MAC address then the i40e driver needs to halt the VF device so that the administrator will be forced to reload the VF driver. This will cause the VF driver to start using the newly assigned MAC address. This brings the i40e driver into conformance with operational characteristics of other Intel SR-IOV featured drivers.
