From 6e0acecbacdb5bf1ce0b71d4c2512eae4606be57 Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Mon, 3 Apr 2017 09:47:08 +0200 Subject: [PATCH] interface-ip: fix device name for IPv6 link-local DNS server Commit 235a02424c3ab1b59308895c4f00395dacf2557c adds support for IPv6 link-local DNS server by appending the device name; however the interface ifname parameter does not always contain the layer 3 device name (e.g it can hold the aliased interface name) Fix this by passing the device name of the referenced layer 3 device.
