CPSW switchdev based driver which is operating in dual-emac mode by
default, thus working as 2 individual network interfaces. The Switch mode
can be enabled by configuring devlink driver parameter "switch_mode" to 1:
devlink dev param set platform/48484000.switch \
name switch_mode value 1 cmode runtime
This can be done regardless of the state of Port's netdevs - UP/DOWN, but
Port's netdev devices have to be UP before joining the bridge to avoid
overwriting of bridge configuration as CPSW switch driver completely
reloads its configuration when first Port changes its state to UP.
When the both interfaces joined the bridge - CPSW switch driver will start
marking packets with offload_fwd_mark flag unless "ale_bypass=0".
All configuration is implemented via switchdev API and notifiers.
Supported:
- SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS
- SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS: BR_MCAST_FLOOD
- SWITCHDEV_ATTR_ID_PORT_STP_STATE
- SWITCHDEV_OBJ_ID_PORT_VLAN
- SWITCHDEV_OBJ_ID_PORT_MDB
- SWITCHDEV_OBJ_ID_HOST_MDB
Hence CPSW switchdev driver supports:
- FDB offloading
- MDB offloading
- VLAN filtering and offloading
- STP

Part 1:
Introduce basic CPSW dual_mac driver (cpsw_new.c) which is operating in
dual-emac mode by default, thus working as 2 individual network interfaces.
Main differences from legacy CPSW driver are:
- optimized promiscuous mode: The P0_UNI_FLOOD (both ports) is enabled in
addition to ALLMULTI (current port) instead of ALE_BYPASS. So, Ports in
promiscuous mode will keep possibility of mcast and vlan filtering, which
is provides significant benefits when ports are joined to the same bridge,
but without enabling "switch" mode, or to different bridges.
- learning disabled on ports as it make not too much sense for
segregated ports - no forwarding in HW.
- enabled basic support for devlink.

Add bindings for the new TI CPSW switch driver. Comparing to the legacy
bindings (net/cpsw.txt):
- ports definition follows DSA bindings (net/dsa/dsa.txt) and ports can be
marked as "disabled" if not physically wired.
- all deprecated properties dropped;
- all legacy propertiies dropped which represent constant HW cpapbilities
(cpdma_channels, ale_entries, bd_ram_size, mac_control, slaves,

- TI CPTS DT properties are reused as is, but grouped in "cpts" sub-node

A following patches introduce new CPSW switchdev driver which uses common

CPSW switchdev and CPSW legacy drivers related to for_each_slave() and
cpsw_slave_index() - they can be compiled both, but only one of them will
be not functional depending in Kconfig settings due to duffrences in Slave
Ports indexes calculation.
To fix this make for_each_slave() local (it's used now only by legacy CPSW

assigned in probe. Driver to probe is defined by DT.

On the NXP LS1028A, there are 2 Ethernet links between the Felix switch
and the ENETC:
- eno2 <-> swp4, at 2.5G
- eno3 <-> swp5, at 1G
Only one of the above Ethernet port pairs can act as a DSA link for
tagging.
When adding initial support for the driver, it was tested only on the 1G
eno3 <-> swp5 interface, due to the necessity of using PHYLIB initially
(which treats fixed-link interfaces as emulated C22 PHYs, so it doesn't
support fixed-link speeds higher than 1G).
After making PHYLINK work, it appears that swp4 still can't act as CPU
port. So it looks like ocelot_set_cpu_port was being called for swp4,
but then it was called again for swp5, overwriting the CPU port assigned
in the DT.
It appears that when you call dsa_upstream_port for a port that is not
defined in the device tree (such as swp5 when using swp4 as CPU port),
its dp->cpu_dp pointer is not initialized by dsa_tree_setup_default_cpu,
and this trips up the following condition in dsa_upstream_port:
if (!cpu_dp)
return port;
So the moral of the story is: don't call dsa_upstream_port for a port
that is not defined in the device tree, and therefore its dsa_port
structure is not completely initialized (ds->num_ports is still 6).

Patches #1-#2 from Danielle add the router scale test for Spectrum-2. It

* Differentiate between supported and advertised speeds and use the

When looking at the details I realised that the memory poison in

SLUB allocator uses the first 16 bytes (on 64 bit), for its freelist,
which overlap with members in struct xdp_mem_allocator, that were
updated. Thus, SLUB already does the "poisoning" for us.
I still believe that poisoning memory make sense in other cases.
Kernel have gained different use-after-free detection mechanism, but
enabling those is associated with a huge overhead. Experience is that
debugging facilities can change the timing so much, that that a race
condition will not be provoked when enabled. Thus, I'm still in favour
of poisoning memory where it makes sense.

We currently match clause 45 PHYs using any ID read from a MMD marked
as present in the "Devices in package" registers 5 and 6. However,
this is incorrect. 45.2 says:
"The definition of the term package is vendor specific and could be
a chip, module, or other similar entity."
so a package could be more or less than the whole PHY - a PHY could be
made up of several modules instantiated onto a single chip such as the
Marvell 88x3310, or some of the MMDs could be disabled according to
chip configuration, such as the Broadcom 84881.
In the case of Broadcom 84881, the "Devices in package" registers
contain 0xc000009b, meaning that there is a PHYXS present in the
package, but all registers in MMD 4 return 0xffff. This leads to our
matching code incorrectly binding this PHY to one of our generic PHY
drivers.
This patch changes the way we determine whether to attempt to match a
MMD identifier, or use it to request a module - if the identifier is
all-ones, then we skip over it. When reading the identifiers, we
initialise phydev->c45_ids.device_ids to all-ones, only reading the
device ID if the "Devices in package" registers indicates we should.
This avoids the generic drivers incorrectly matching on a PHY ID of
0xffffffff.
