[PATCH] set a destination for the IPv6 default gateway

[Mathieu Trudel-Lapierre <mathieu-tl ubuntu com>]

Hi,

The attached patch appears to be required for setting the default
gateway for IPv6 with libnl3 (tested with libnl3 3.0). It comes with a
small fix to catch the return code for nm_netlink_route_add() so
success is correctly reported as such (or to get the "right" error
message).

Regards,
