Subject: [PATCH net-next 0/8] 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 4 patches 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.

Vivien Didelot (8):
  net: dsa: directly fetch switch in mtk_tag_rcv
  net: dsa: directly fetch switch in lan9303_rcv
  net: dsa: use cpu_dp in master code
  net: dsa: use temporary dsa_device_ops variable
  net: dsa: add tagging ops to port
  net: dsa: prepare master receive hot path
  net: dsa: change dsa_ptr for a dsa_port
  net: dsa: remove tag ops from the switch tree
