From 3d00ccaaab8263752cd343dea55b7bd0072a3fae Mon Sep 17 00:00:00 2001

Subject: [PATCH] * Add get_nameservers() which processes
 /var/etc/nameserver_$interface * Use get_nameservers() instead of
 nameserver.conf since we may be in a multi-wan situation * Only populate
 $master_list when item is <> ""
