From 28e3b328545529c19429ce88c7d1769e64e2de0f Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Mon, 12 Mar 2018 16:12:18 +0100 Subject: [PATCH] treewide: unify mac address handling Use the new luci.ip MAC address facilities to parse and verify MAC addresses in a common way, instead of relying on various ad-hoc solutions.
