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
Vivien Didelot (7): net: dsa: add master helper to look up slaves 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
