Subject: [patch net-next 07/16] mlxsw: spectrum_router: Extract mlxsw_sp_ipip_entry_ol_up_event()

From: Petr Machata <petrm@...lanox.com>

The piece of logic to promote decap route, if any, is useful for generic
tunnel updates, not just for handling of NETDEV_UP events on tunnel
interfaces. Extract it to a separate function.
