> With DSA, a master net_device is physically wired to a dedicated CPU

> 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

> 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.
