[PATCH net-next 06/10] mlxsw: spectrum: Move handling of tunnel events to router code

[Ido Schimmel <idosch@nvidia.com>]

From: Petr Machata <petrm@nvidia.com>

The events related to IPIP tunnels are handled by the router code. Move the
handling from the central dispatcher in spectrum.c to the new notifier
handler in the router module.
