mlxsw: spectrum: Add router interface struct

Browse source

When enabling the router in the device we will represent L3 netdevs
using router interfaces (RIFs). These will be specified whenever
programming routes or neighbours on the netdev.

Introduce the basic RIF infrastructure which allows one to lookup a RIF
by its netdev. Later patches in the series will extend this, but the
basic routines are needed now in order to direct traffic to CPU.

Pointers to the RIF structs are stored in an array indexed by the RIF's
number. This will allow us to efficiently update the kernel's neighbour
table when regularly dumping the device's table.
