FS#597 - Unchecking "Use DNS servers advertised by peer" has no effect for IPv6

Hi everyone,

When the option “Use DNS servers advertised by peer” has been unchecked, LEDE still writes the advertised peer DNS Servers for v6 into /tmp/

# Interface wan
# Interface wan_6
nameserver xxx
nameserver xxx

The IPv4 nameservers just disappear in this file, and on the overview page, these two v6 DNS Servers still appear on the “network” section (without their v4 counterparts).

To actually force dnsmasq to ignore these two, I have to check “Ignore resolve file” in the dnsmasq configuration.

I’m running LuCI lede-17.01 branch (git-17.051.53299-a100738) / LEDE Reboot 17.01.0-rc2 r3131-42f3c1f on a Linksys 1900ACS v2.

My WAN connection is a PPPoE connection with “Use builtin IPv6-management” checked and the option below set to “automatic”.
