In the router, some next hops may reference an encapsulating netdevice, such as GRE or IPIP. To properly offload these next hops, mlxsw needs to keep track of whether a given next hop is a regular Ethernet entry, or an IP-in-IP tunneling entry. To facilitate this book-keeping, add a type field to struct mlxsw_sp_nexthop. There is, as of this patch, only one next hop type: MLXSW_SP_NEXTHOP_TYPE_ETH. Follow-up patches will introduce the IP-in-IP variant. There are several places where next hops are initialized in the IPv4 path. Instead of replicating the logic at every one of them, factor it out to a function mlxsw_sp_nexthop4_type_init(). The corresponding fini is actually protocol-neutral, so put it to mlxsw_sp_nexthop_type_fini(), but create a corresponding protocoled _fini function that dispatches to the protocol-neutral one. The IPv6 path is simpler, but for symmetry with IPv4, create the same suite of functions with corresponding logic.
