From 9de40c87dd6daa8d1e1727094e12b86406cc7948 Mon Sep 17 00:00:00 2001
From: Bill Nottingham <notting@redhat.com>

Subject: fix grep to always match the full hwaddr, as opposed to matching '0'
 against '00:AA:BB:CC:DD:EE'. Take into account lines that end with spaces, or
 with "# this is a comment", too. Also, put the grep in only one place instead
 of 3. Fixes #157252, #153669.
