[RFC PATCH net-next v2 00/10] net: dsa: b53: fix BCM5325 support

[Álvaro Fernández Rojas]

These patches get the BCM5325 switch working with b53.

I'm not really sure that everything here is correct since I don't work for
Broadcom and all this is based on the public datasheet available for the
BCM5325 and my own experiments with a Huawei HG556a (BCM6358).

 v2: introduce changes requested by Jonas, Florian and Vladimir:
  - Add b53_arl_to_entry_25 function.
  - Add b53_arl_from_entry_25 function.
  - Add b53_arl_read_25 function, fixing usage of ARLTBL_VALID_25 and
    ARLTBL_VID_MASK_25.
  - Change b53_set_forwarding function flow.
  - Disallow BR_LEARNING on b53_br_flags_pre() for BCM5325.
  - Drop rate control registers.
  - Move B53_PD_MODE_CTRL_25 to b53_setup_port().
