mlxsw: spectrum: Keep mirror netdev in mlxsw_sp_span_entry
Currently the only mirror action supported by mlxsw is mirror to another
mlxsw physical port. Correspondingly, span_entry, which tracks each
mlxsw mirror in the system, currently holds a u8 number of the
destination port.
To extend this system to mirror to gretap and ip6gretap netdevices, have
struct mlxsw_sp_span_entry actually hold the destination netdevice
itself.
This change then trickles down in obvious manner to SPAN module API and
mirror-related interfaces in struct mlxsw_afa_ops.
To prevent use of invalid pointer, NETDEV_UNREGISTER needs to be hooked
and the corresponding SPAN entry invalidated.
