Netlink support was added to FreeBSD recently. It is not as full-featured as its Linux counterpart yet, however the added subset is enough to make a routing daemon work. Specifically, it supports multiple tables, multipath, nexthops and nexthops groups. No MPLS support yet. The attached change adds 'bsd-netlink’ sysconf target, allowing to build both netlink & rtsock versions on FreeBSD.
