From bcab2db97d2423b97b248ba35eb2277168e71fcc Mon Sep 17 00:00:00 2001 From: Carolyn Wyborny Date: Mon, 28 Sep 2015 14:16:55 -0400 Subject: [PATCH] i40e: Fix for Tools loopback test failing after driver load This patch fixes a problem where our Tools MAC Loopback test, after driver unbind would fail. This was because the hw was configured for multiqueue and unbind operation did not clear this configuration. The problem is fixed by resetting this configuration in i40e_remove.
