Hi,
I made a patch in connman that might be useful for others.
I noticed that connman has an option FallbackNameservers which is currently
only used in tethering mode.
I made a patch that also uses this the nameservers given with the
FallbackNameservers in case any other nameserver (returned by the DHCP server)
fails. This can be very useful in network where DNS requests to external
addresses are not forwarded.
Patch is made on connman 1.9 but is still valid on latest connman version.
I'll let community decide whether this is suitable for mainstream connman code
or just custom patch.
