      ====================
      net: dsa: change dsa_ptr for a dsa_port
      
      With DSA, a master net_device is physically wired to a dedicated CPU
      switch port. For interaction with the DSA layer, the struct net_device
      contains a dsa_ptr, which currently points to a dsa_switch_tree object.
      
      This is only valid for a switch fabric with a single CPU port. In order
      to support switch fabrics with multiple CPU ports, we first need to
      change the type of dsa_ptr to what it really is: a dsa_port object.
      
      This is what this patchset does. The first patches adds a
      dsa_master_get_slave helper and cleans up portions of DSA core to make
      the next patches more readable. These next patches prepare the xmit and
      receive hot paths and finally change dsa_ptr.
      
      Changes in v2:
        - introduce dsa_master_get_slave helper to simplify patch 6
        - keep hot path data at beginning of dsa_port for cacheline 1
