Subject: [PATCH iproute2-next] ip route: Print "rt_offload" and "rt_trap" indication

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

The kernel now signals the offload state of a route using the
'RTM_F_OFFLOAD' and 'RTM_F_TRAP' flags. Print these to help users
understand the offload state of each route. The "rt_" prefix is used in
order to distinguish it from the offload state of nexthops.
