These are Gen3 Aquantia N-BASET PHYs which support 5GBASE-T,
2.5GBASE-T, 1000BASE-T and 100BASE-TX (not 10G); also EEE, Sync-E,
PTP, PoE.

The 112 is a single PHY package, the 412 is a quad PHY package.

The system-side SERDES interface of these PHYs selects its protocol
depending on the negotiated media side link speed. That protocol can be
1000BASE-X, 2500BASE-X, 10GBASE-R, SGMII, USXGMII.

The configuration of which SERDES protocol to use for which link speed
is made by firmware; even though it could be overwritten over MDIO by
Linux, we assume that the firmware provisioning is ok for the board on
which the driver probes.

For cases when the system side runs at a fixed rate, we want phylib/phylink
to detect the PAUSE rate matching ability of these PHYs, so we need to
use the Aquantia rather than the generic C45 driver. This needs
aqr107_read_status() -> aqr107_read_rate() to set phydev->rate_matching,
as well as the aqr107_get_rate_matching() method.

I am a bit unsure about the naming convention in the driver. Since
AQR107 is a Gen2 PHY, I assume all functions prefixed with "aqr107_"
rather than "aqr_" mean Gen2+ features. So I've reused this naming
convention.

I've tested PHY "SGMII" statistics as well as the .link_change_notify
method, which prints:

Aquantia AQR412 mdio_mux-0.4:00: Link partner is Aquantia PHY, FW 4.3, fast-retrain downshift advertised, fast reframe advertised

Tested SERDES protocols are usxgmii and 2500base-x (the latter with
PAUSE rate matching). Tested link modes are 100/1000/2500 Base-T
(with Aquantia link partner and with other link partners). No notable
events observed.

The placement of these PHY IDs in the driver is right before AQR113C,
a Gen4 PHY.

net: Add support for sorted VCAP rules in Sparx5

This provides support for adding Sparx5 VCAP rules in sorted order, VCAP
rule counters and TC filter matching on ARP frames.

It builds on top of the initial IS2 VCAP support found in these series:

https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/

Functionality
=============

When a new VCAP rule is added the driver will now ensure that the rule is
inserted in sorted order, and when a rule is removed, the remaining rules
will be moved to keep the sorted order and remove any gaps in the VCAP
address space.

A VCAP rule is ordered using these 3 values:

 - Rule size: the count of VCAP addresses used by the rule.  The largest
   rule have highest priority

 - Rule User: The rules are ordered by the user enumeration

 - Priority: The priority provided in the flower filter.  The lowest value
   has the highest priority.

A VCAP instance may contain the counter as part of the VCAP cache area, and
this counter may be one or more bits in width.  This type of counter
automatically increments its value when the rule is hit.

Other VCAP instances have a dedicated counter area outside of the VCAP and
in this case the rule must contain the counter id to be able to locate the
counter value and cause the counter to be incremented.  In this case there
must also be a VCAP rule action that sets the counter id.

The Sparx5 IS2 VCAP uses a dedicated counter area with 32bit counters.

This series adds support for getting VCAP rule counters and provide these
via the TC statistic interface.

This only support packet counters, not byte counters.

Finally the series adds support for the ARP frame dissector and configures
the Sparx5 IS2 VCAP to generate the ARP keyset when ARP traffic is
received.

Delivery:
=========

This is current plan for delivering the full VCAP feature set of Sparx5:

- DebugFS support for inspecting rules
- TC protocol all support
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
  upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support

NOTE: If irqbalance is running, you need to stop it from overriding
