[patch net-next v3 8/9] mlxsw: spectrum: Mark unused ports using NULL

[Jiri Pirko]

From: Ido Schimmel <ido...@mellanox.com>

When splitting and unsplitting we'll destroy usable ports on the fly, so
mark them using a NULL pointer to indicate that their local port number
is free and can be re-used.
