From: "Dr. David Alan Gilbert" <linux@treblig.org>

mlxsw_sp_ipip_lb_ul_vr_id() has been unused since 2020's
commit acde33bf7319 ("mlxsw: spectrum_router: Reduce
mlxsw_sp_ipip_fib_entry_op_gre4()")

mlxsw_sp_rif_exists() has been unused since 2023's
commit 49c3a615d382 ("mlxsw: spectrum_router: Replay MACVLANs when RIF is
made")

mlxsw_sp_rif_vid() has been unused since 2023's
commit a5b52692e693 ("mlxsw: spectrum_switchdev: Manage RIFs on PVID
change")

Remove them.
