Log: Enable ROUTE_MPATH support in GENERIC kernels. Ability to load-balance traffic over multiple path is a must-have thing for routers. It may be used by the servers to balance outgoing traffic over multiple default gateways. The previous implementation, RADIX_MPATH stayed in the shadow for too long. It was not well maintained, which lead us to a vicious circle - people were using non-contiguous mask or firewalls to achieve similar goals. As a result, some routing daemons implementation still don't have multipath support enabled for FreeBSD. Turning on ROUTE_MPATH by default would fix it. It will allow to reduce networking feature gap to other operating systems. Linux and OpenBSD enabled similar support at least 5 years ago. ROUTE_MPATH does not consume memory unless actually used. It enables around ~1k LOC. It does not bring any behaviour changes for userland. Additionally, feature is (temporarily) turned off by the net.route.multipath sysctl defaulting to 0.
