Merge branch 'net-dsa-b53-fix-bcm5325-support'
Álvaro Fernández Rojas says:
====================
net: dsa: b53: fix BCM5325 support
These patches get the BCM5325 switch working with b53.
The existing brcm legacy tag only works with BCM63xx switches.
We need to add a new legacy tag for BCM5325 and BCM5365 switches, which
require including the FCS and length.
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).
Both sets of patches have been merged due to the change requested by Jonas
about BRCM_HDR register access depending on legacy tags.
