146a32067b net: dsa: add port_fdb_prepare
Push the prepare phase for FDB operations down to the DSA drivers, with
a new port_fdb_prepare function. Currently only mv88e6xxx is affected.

4bac50bace net: dsa: mv88e6xxx: remove link polling
The link status is polled by the generic phy layer, there's no need to
duplicate that polling with additional polling.  This additional polling
adds additional MDIO traffic, and races with the generic phy layer,
resulting in missing or duplicated link status messages.

The Marvell 88E6171 switch is in the 88E6351 family, which supports
802.1Q, thus add support from the generic mv88e6xxx functions.

dea870242a dsa: mv88e6xxx: Allow speed/duplex of port to be configured
The current code sets user ports to perform auto negotiation using the
phy. CPU and DSA ports are configured to full duplex and maximum speed
the switch supports.

There are however use cases where the CPU has a slower port, and when
user ports have SFP modules with fixed speed. In these cases, port
settings to be read from a fixed_phy devices. The switch driver then
needs to implement the adjust_link op, so the port settings can be
set.

2a778e1b58 net: dsa: change FDB routines prototypes
Change the prototype of port_getnext to include a vid parameter.

This is necessary to introduce the support for VLAN.

Also rename the fdb_{add,del,getnext} function pointers to
port_fdb_{add,del,getnext} since they are specific to a given port.

6630e23617 net: dsa: mv88e6xxx: rework FDB getnext operation
This commit adds a low level _mv88e6xxx_atu_getnext function and helpers
to rewrite the mv88e6xxx_port_fdb_getnext operation.

A mv88e6xxx_atu_entry structure is added for convenient access to the
hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value.

The previous implementation did not handle the eventual trunk mapping.
If the related bit is set, then the ATU data register would contain the
trunk ID, and not the port vector.

Check this in the FDB getnext operation and do not handle it (yet).

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.

c146b7788e dsa: mv88e6171: Fix tagging protocol/Kconfig
The mv88e6171 can support two different tagging protocols, DSA and
EDSA. The switch driver structure only allows one protocol to be
enumerated, and DSA was chosen. However the Kconfig entry ensures the
EDSA tagging code is built. With a minimal configuration, we then end
up with a mismatch. The probe is successful, EDSA tagging is used, but
the switch is configured for DSA, resulting in mangled packets.

Change the switch driver structure to enumerate EDSA, fixing the
mismatch.

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.
