Vivien Didelot 17a1594e2d net: dsa: mv88e6xxx: program the PVT with all ones
The Cross-chip Port Based VLAN Table (PVT) is currently initialized with
all ones, allowing any external ports to egress frames on local ports.

This commit implements the PVT access functions and programs the PVT
with all ones for the local switch ports only, instead of using the Init
operation. The current behavior is unchanged for the moment.

Vivien Didelot 812289960f net: dsa: mv88e6xxx: use 4-bit port for PVT data
The Cross-chip Port Based VLAN Table (PVT) supports two indexing modes,
one using 5-bit for device and 4-bit for port, the other using 4-bit for
device and 5-bit for port, configured via the Global 2 Misc register.

Only 4 bits for the source port are needed when interconnecting 88E6xxx
switch devices since they all support less than 16 physical ports. The
full 5 bits are needed when interconnecting a device with 98DXxxx switch
devices since they support more than 16 physical ports.

Add a mv88e6xxx_pvt_setup helper to set the 4-bit port PVT mode, which
will be extended later to also initialize the PVT content.

Vivien Didelot f364565221 net: dsa: mv88e6xxx: move PVT description in info
Not all Marvell switch chips feature a Cross-chip Port VLAN Table (PVT).

Chips with a PVT use the same implementation, so a new mv88e6xxx_ops
member won't be necessary yet. Add a "pvt" boolean member to the
mv88e6xxx_info structure and kill the obsolete MV88E6XXX_FLAGS_PVT flag.

Add a mv88e6xxx_has_pvt helper to wrap future checks of that condition.

Add a debug message to inform the user about the exact programmed value.

Andrew Lunn c6e970a04b net: break include loop netdevice.h, dsa.h, devlink.h
There is an include loop between netdevice.h, dsa.h, devlink.h because
of NETDEV_ALIGN, making it impossible to use devlink structures in
dsa.h.

Break this loop by taking dsa.h out of netdevice.h, add a forward
declaration of dsa_switch_tree and netdev_set_default_ethtool_ops()
function, which is what netdevice.h requires.

No longer having dsa.h in netdevice.h means the includes in dsa.h no
longer get included. This breaks a few other files which depend on
these includes. Add these directly in the affected file.

Vivien Didelot 601aeed371 net: dsa: mv88e6xxx: fix port egress flooding mode
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.

Andrew Lunn f39908d3b1 net: dsa: mv88e6xxx: Set the CMODE for mv88e6390 ports 9 & 10
Unlike most ports, ports 9 and 10 of the 6390X family have configurable
PHY modes. Set the mode as part of adjust_link().

Ordering is important, because the SERDES interfaces connected to
ports 9 and 10 can be split and assigned to other ports. The CMODE has
to be correctly set before the SERDES interface on another port can be
configured. Such configuration is likely to be performed in
port_enable() and port_disabled(), called on slave_open() and
slave_close().

The simple case is port 9 and 10 are used for 'CPU' or 'DSA'. In this
case, the CMODE is set via a phy-mode in dsa_cpu_dsa_setup(), which is
called early in the switch setup.

When ports 9 or 10 are used as user ports, and have a fixed-phy, when
the fixed fixed-phy is attached, dsa_slave_adjust_link() is called,
which results in the adjust_link function being called, setting the
cmode. The port_enable() will for other ports will be called much
later.

When ports 9 or 10 are used as user ports and have a real phy attached
which does not use all the available SERDES interface, e.g. a 1Gbps
SGMII, there is currently no mechanism in place to set the CMODE of
the port from software. It must be hoped the stripping resistors are
correct.

At the same time, add a function to get the cmode. This will be needed
when configuring the SERDES interfaces.

Marvell chips have different way to issue a software reset.

Old chips (such as 88E6060) have a reset bit in an ATU control register.

Newer chips moved this bit in a Global control register. Chips with
controllable PPU should reset the PPU when resetting the switch.

Add a new reset operation to implement these differences and introduce a
mv88e6xxx_software_reset() helper to wrap it conveniently.

David S. Miller f9aa9dc7d2 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
All conflicts were simple overlapping changes except perhaps
for the Thunder driver.

That driver has a change_mtu method explicitly for sending
a message to the hardware.  If that fails it returns an
error.

Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.

However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Florian Fainelli e47112d9d6 net: dsa: b53: Fix VLAN usage and how we treat CPU port
We currently have a fundamental problem in how we treat the CPU port and
its VLAN membership. As soon as a second VLAN is configured to be
untagged, the CPU automatically becomes untagged for that VLAN as well,
and yet, we don't gracefully make sure that the CPU becomes tagged in
the other VLANs it could be a member of. This results in only one VLAN
being effectively usable from the CPU's perspective.

Instead of having some pretty complex logic which tries to maintain the
CPU port's default VLAN and its untagged properties, just do something
very simple which consists in neither altering the CPU port's PVID
settings, nor its untagged settings:

- whenever a VLAN is added, the CPU is automatically a member of this
  VLAN group, as a tagged member
- PVID settings for downstream ports do not alter the CPU port's PVID
  since it now is part of all VLANs in the system

This means that a typical example where e.g: LAN ports are in VLAN1, and
WAN port is in VLAN2, now require having two VLAN interfaces for the
host to properly terminate and send traffic from/to.

Vivien Didelot 96a2b40c7b net: dsa: mv88e6xxx: add port's MAC speed setter
While the two bits for link, duplex or RGMII delays are used the same
way on chips supporting the said feature, the two bits for speed have
different meaning for most of the chips out there.

Speed value is stored in bits 1:0, 0x3 means unforce (normal detection).

Some chips reuse values for alternative speeds when bit 12 is set.

Newer chips with speed > 1Gbps reuse value 0x3 thus need a new bit 13.

Here are the values to write in register 0x1 to (un)force speed:

    | Speed   | 88E6065 | 88E6185 | 88E6352 | 88E6390 | 88E6390X |
    | ------- | ------- | ------- | ------- | ------- | -------- |

Vivien Didelot a0a0f6229b net: dsa: mv88e6xxx: add port's RGMII delay setter
Some chips such as 88E6352 and 88E6390 can be programmed to add delays
to RXCLK for IND inputs or to GTXCLK for OUTD outputs when port is in
RGMII mode.

Add a port function to program such delays according to the provided PHY
interface mode.

Florian Fainelli 4a2947e32e net: dsa: bcm_sf2: Do not rely on kexec_in_progress
After discussing with Eric, it turns out that, while using
kexec_in_progress is a nice optimization, which prevents us from always
powering on the integrated PHY, let's just turn it on in the shutdown
path.

This removes a dependency on kexec_in_progress which, according to Eric
should not be used by modules

Florian Fainelli 2399d6143f net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels
For a kernel that is being kexec'd we re-enable the integrated GPHY in
order for the subsequent MDIO bus scan to succeed and properly bind to
the bcm7xxx PHY driver. If we did not do that, the GPHY would be shut
down by the time the MDIO driver is probing the bus, and it would fail
to read the correct PHY OUI and therefore bind to an appropriate PHY
driver. Later on, this would cause DSA not to be able to successfully
attach to the PHY, and the interface would not be created at all.

rather than polling, speeding up PHY handling and reducing load on the

This commit removes explicit includes except the following:

These two are used for host programs.

The mv88e6xxx_ops is used to describe how to access the chip registers.
It can be through SMI (via an MDIO bus), or via another interface such
as crafted remote management frames.

The correct BUS operations structure is chosen at runtime, depending on

We will need the mv88e6xxx_ops name for future chip-wide operation
structure, thus rename mv88e6xxx_ops to more explicit mv88e6xxx_bus_ops.
