From 41d0a4d0c8b144e44d92ea95e975d2434748d806 Mon Sep 17 00:00:00 2001 From: Alan Brady Date: Tue, 22 Aug 2017 06:57:52 -0400 Subject: [PATCH] i40e: fix handling of vf_states variable Currently we inappropriately clear the vf_states variable with a null assignment. This is problematic because we should be using atomic bitops on this variable and we don't actually want to clear all the flags. We should just clear the ones we know we want to clear. Additionally remove the I40E_VF_STATE_FCOEENA bit because it is no longer being used.
