> 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

Series applied, thank you.
