15966a2a76 net: dsa: Converting remaining registers to mnemonics
Use defines for registers, shifts and bits in the remaining register
accesses in the individual drivers, in order to aid readability.

54d792f257 net: dsa: Centralise global and port setup code into mv88e6xxx.
The port setup code in the individual drivers is identical for 6123,
6171, and 6352, and very similar in 6131. Move it all into mv88e6xxx,
using the chip families to differentiate on features.

Similarly, the global setup is also very similar. Move the majority
into mv8e6xxx.

The chips themselves fall into families. Add helpers which uses the
device IDs to determine if a device is a member of a family or not.
Add some additional device IDs to the existing list, to make these
helper functions more complete. However these IDs are not yet added to
the probe functions.

b4d2394d01 dsa: Replace mii_bus with a generic host device
This change makes it so that instead of passing and storing a mii_bus we
instead pass and store a host_dev.  From there we can test to determine the
exact type of device, and can verify it is the correct device for our switch.

So for example it would be possible to pass a device pointer from a pci_dev
and instead of checking for a PHY ID we could check for a vendor and/or device
ID.

ac7a04c33d net: dsa: change tag_protocol to an enum
Now that we introduced an additional multiplexing/demultiplexing layer
with commit 3e8a72d1da ("net: dsa: reduce number of protocol hooks")
that lives within the DSA code, we no longer need to have a given switch
driver tag_protocol be an actual ethertype value, instead, we can
replace it with an enum: dsa_tag_protocol.

Do this replacement in the drivers, which allows us to get rid of the
cpu_to_be16()/htons() dance, and remove ETH_P_BRCMTAG since we do not
need it anymore.
