Subject: [patch net-next 1/6] ipv4: fib: Set offload indication according to nexthop flags

From: Ido Schimmel <idosch@...lanox.com>

We're going to have capable drivers indicate route offload using the
nexthop flags, but for non-multipath routes these flags aren't dumped to
user space.

Instead, set the offload indication in the route message flags.
