I'm providing a resolv.conf with four entries via the resolv-file option.
Unfortunately the first two entries are the only ones that are considered, as
verified via tshark.

The reason for the setup is as follows: We have two uplinks, each having two DNS
servers available only via that uplink. When the first uplink goes down, the
first two DNS server entries become unresponsive.

The workaround I've used is two interleave both files, but it would still be
great to be able to configure more than two upstream DNS servers.
