linux-cp: Handle RTA_VIA routes.
RTA_VIA allows routes to have a next-hop in a different address family. This commit makes linux-cp import those types of routes correctly, instead of importing the routes without a gateway. This uses rtnl_route_nh_get_gateway, which is available since libnl 3.4.0 (Oct. 9, 2017). Even Debian Stretch has it via backports. Type: fix Change-Id: I06297c700461ba7874eb8baf9355bd40990b3121 Signed-off-by: Adrian Pistol <vifino@posteo.net>
