[patch net-next 5/6] mlxsw: spectrum_router: Refresh offload indication upon group refresh

[Jiri Pirko]

From: Ido Schimmel <ido...@mellanox.com>

Now that we provide offload indication using the nexthop's flags we must
refresh the offload indication whenever the offload state within the
group changes.

This didn't matter until now, as offload indication was provided using
the FIB info flags and multipath routes were marked as offloaded as long
as one of the nexthops was offloaded.
