[PATCH net-next v2 00/17] net: dsa: mv88e6xxx: rework ATU support

[Vivien Didelot]

The purpose of this patch series is to rework the code related to the
Address Translation Unit (ATU), and bring support for it to the 88E6390
family of switch chips.

All Global (1) ATU related code have been reworked and moved to its own
file. Some port related bits used for ATU configuration (such as the
Learn2All and MessagePort feature) have also been taken care of.

The ports' mode and egress flooding mode have been refactored to fix the
egress of frames with unknown unicast or multicast destination address,
and write all these bits regardless the port mode (Normal, DSA, etc.)

Finally remove the eth_addr_greater which was only used by mv88e6xxx.

Changes in v2:
  - add Reviewed-by tags
  - split mv88e6xxx_g1_atu_set_age_time and mv88e6xxx_atu_setup addition
  - remove DSA_TAG_PROTO_TRAILER check
  - split Message Port and Learn2All addition
  - remove unused MV88E6XXX_FLAG_G1_ATU_FID flag
  - add dsa_is_normal_port helper

[PATCH net-next v2 01/17] net: dsa: mv88e6xxx: add port mask helper

[Vivien Didelot]

Add a mv88e6xxx_port_mask() helper to get the bitmask of ports in a
switch chip, that will be used in several features.

[PATCH net-next v2 03/17] net: dsa: mv88e6xxx: add ATU setup helper

[Vivien Didelot]

Move the configuration of the default ageing time in a new
mv88e6xxx_atu_setup function.

That function will be extended later to contain all ATU related
configuration bits.

[PATCH net-next v2 04/17] net: dsa: mv88e6xxx: setup message ports

[Vivien Didelot]

All interconnectable Marvell switch chips have an ATU Learn2All feature
which allows newly learnt addresses to be spanned on ports marked as
"Message Port".

This commit configures the DSA ports as Message Port. Note that this has
no effect until the Learn2All feature is enabled.

[PATCH net-next v2 06/17] net: dsa: mv88e6xxx: rework ATU Load/Purge

[Vivien Didelot]

All Marvell switch chips have an ATU accessed using the same Global (1)
register layout. Only the handling of the FID differs as more bits were
necessary to support more and more databases.

Add and use a fresh documented implementation of the ATU Load/Purge.

The static mv88e6xxx_g1_atu_{fid_write,op_wait,op,data_write,mac_write}
functions won't need to be exposed in the end so for the moment keep
their counterparts _mv88e6xxx_atu_{wait,cmd,data_write,mac_write} as is,
since they are still used by other ATU operations.

[PATCH net-next v2 07/17] net: dsa: mv88e6xxx: rework ATU GetNext

[Vivien Didelot]

Add and use a fresh documented implementation of the ATU GetNext.

Since it is not necessary to write the MAC address to iterate from, only
do it once directly in the ATU GetNext operation, if the provided ATU
entry structure is not valid. This makes the user code simpler.

Also, there is no need to loop when getting a single ATU entry. So
remove the mv88e6xxx_atu_get helper and add a simpler snippet in
mv88e6xxx_port_db_load_purge to lookup a given MAC address.

The _mv88e6xxx_atu_mac_{read,write} are not used anymore thus remove
them. _mv88e6xxx_atu_data_{read,write} are still used so keep them.

Add a fresh documented implementation of the ATU Flush/Move operation.
Use it to replace the current ATU Flush operation.

_mv88e6xxx_atu_flush_move is still used by the Move operation so keep it
until the Move operation is refactored in a next commit.

[PATCH net-next v2 09/17] net: dsa: mv88e6xxx: rework ATU Remove

[Vivien Didelot]

Add a fresh documented implementation of the ATU Move operation, and use
it to replace the current ATU Remove operation.

Note that not all Marvell switch chip support the ATU Move operation.
For those supporting it, the number of bits used to mask the destination
port may vary. 6352 and such use 4-bit, while 6390 use 5-bit. Thus add a
new atu_move_port_mask member in the info structure to describe the
presence and variant of ATU Move operation.

Note that the ATU Move operation is not documented in the 6185 datasheet
but the chip does support the operation.

All remaining _mv88e6xxx_atu_* functions are now unused as well as the
MV88E6XXX_FLAG_G1_ATU_FID flag, thus remove them.

Rename the _mv88e6xxx_fid_new helper to mv88e6xxx_atu_new to get rid of
the old underscore prefix naming convention and be consistent with the

[PATCH net-next v2 11/17] net: dsa: mv88e6xxx: rename the port vector member

[Vivien Didelot]

Not all Marvell switch chips support port trunking, which is embedded in
the port vector data for ATU operations.

Rename the portv_trunkid member of the mv88e6xxx_atu_entry structure to
portvec to be more concise and consistent with the different chips.

net/dsa/dsa2.c uses the "user" terminology should we use something like

I used the one suggested by Andrew, but I wouldn't mind using "user"
here if it makes more sense.

[PATCH net-next v2 13/17] net: dsa: mv88e6xxx: rework port mode setup

[Vivien Didelot]

A switch port mode is defined by the association of its egress mode, its
frame mode and if supported or required, the ether type value.

Pack all this in a mv88e6xxx_set_port_mode function and provide helpers
for the Normal Network mode, the DSA mode, and the Ether Type DSA mode,
as well as an helper to setup a port's mode depending on its nature.

Define PORT_ETH_TYPE_DEFAULT for the 0x9100 reset value of port E Type.

[PATCH net-next v2 14/17] net: dsa: mv88e6xxx: fix port egress flooding mode

[Vivien Didelot]

The Marvell switch ports can be configured to allow or prevent egress of
frames with an unknown unicast or multicast destination address.

Some switch chips such as 88E6095 and 88E6185 have two disjoint bits in
Port Control Register (0x04) bit 2 "Forward Unknown" (for unicast) and
Port Control 2 Register (0x08) bit 6 "Default Forward" (for multicast).

Other chips such as 88E6085, 88E6123, 88E6352, and 88E6390 have a 2-bit
value in Port Control Register (0x04) bits 3:2 "EgressFloods".

The current code does not fully implement the disjoint bits variant and
assigns incorrect ones to some chip models. Fix that with two
implementation references (6185 and 6352 that I currently have) of a
port_set_egress_floods operation (as named in datasheets).

Old chips such as 88E6060 don't have egress flooding mode, so don't
error out if the operation is not provided.

[PATCH net-next v2 15/17] net: dsa: mv88e6xxx: add port ATU learn limit op

[Vivien Didelot]

Add a new operation to disable the limiting of learnt MAC addresses.

Setting such limit is not likely to be used soon, so provide a
port_disable_learn_limit operation directly. This can be changed later
for port_set_learn_limit when we'll need it.

[PATCH net-next v2 16/17] net: dsa: mv88e6xxx: add port priority override op

[Vivien Didelot]

Add a new operation to disable the DA, SA and VTU priority override.

Setting such limit is not likely to be used soon, so provide a
port_disable_pri_override operation directly. This can be changed later
for port_set_pri_override when we'll need it.

Also remove the now obsolete mv88e6xxx_6320_family helper.

[PATCH net-next v2 17/17] etherdevice: remove unused eth_addr_greater

[Vivien Didelot]

eth_addr_greater() was introduced for the mv88e6xxx driver, but is not
used anymore. There is no other user, thus remove this function.

Just some general note on the way the driver seems to be going there
seems to be a multiplication of new ops being introduced, and most of
them seem to default to the mv88e6xxx (generic) ones. Should you do
something like:

if (!ops->foo)
	ops->foo = mv88e6xxx_foo

Such that you reduce the possibility for a specific switch model to lack
such an operation?

You are correct, ideally generic library functions (the one starting
with the mv88e6xxx_ prefix) should not be assigned to ops.

The ops are const though. I'll come up with something maintainable.

Thanks!
