[RFC PATCH net-next 13/15] mlxsw: spectrum_router: Mark routes as "in hardware"

[Ido Schimmel]

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

Make use of the recently introduced APIs and mark notified routes as "in
hardware" after they were programmed to the device's LPM tree.

Similarly, when a route is replaced by an higher priority one, clear the
"in hardware" indication from it.
