At present there are two paths for changing the MTU of the DSA master.
The first is:
dsa_tree_setup
-> dsa_tree_setup_ports
-> dsa_port_setup
-> dsa_slave_create
-> dsa_slave_change_mtu
-> dev_set_mtu(master)
The second is:
dsa_tree_setup
-> dsa_tree_setup_master
-> dsa_master_setup
-> dev_set_mtu(dev)
So the dev_set_mtu() call from dsa_master_setup() has been effectively
superseded by the dsa_slave_change_mtu(slave_dev, ETH_DATA_LEN) that is
done from dsa_slave_create() for each user port. The later function also
updates the master MTU according to the largest user port MTU from the
tree. Therefore, updating the master MTU through a separate code path
isn't needed.
