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.
