From 8db9427d52b894276383091883b6a8bc5bb0c14d Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 16 Jan 2019 23:06:39 +0000 Subject: [PATCH] vxlan: changelink: Inline vxlan_dev_configure() The changelink operation may cause change in remote address, and therefore an FDB update, which can be vetoed. To properly handle vetoing, vxlan_changelink() needs to be gradually updated. In this patch simply replace vxlan_dev_configure() with the two constituent calls.
