Subject: [RFC PATCH 0/3] net: Adding the Sparx5 Switch Driver
This series provides the Microchip Sparx5 Switch Driver
The Sparx5 Carrier Ethernet and Industrial switch family delivers 64 Ethernet
ports and up to 200 Gbps of switching bandwidth.
It provides a rich set of Ethernet switching features such as hierarchical QoS,
hardware-based OAM and service activation testing, protection switching,
IEEE 1588, and Synchronous Ethernet.
Using provider bridging (Q-in-Q) and MPLS/MPLS-TP technology, it delivers MEF CE
2.0 Ethernet virtual connections (EVCs) and features advanced TCAM classification
in both ingress and egress.
Per-EVC features include advanced L3-aware classification, a rich set of
statistics, OAM for end-to-end performance monitoring, and dual-rate policing
and shaping.
Time sensitive networking (TSN) is supported through a comprehensive set of
features including frame preemption, cut-through, frame replication and
elimination for reliability, enhanced scheduling: credit-based shaping,
time-aware shaping, cyclic queuing, and forwarding, and per-stream
policing and filtering.
Together with IEEE 1588 and IEEE 802.1AS support, this guarantees low-latency
deterministic networking for Fronthaul, Carrier, and Industrial Ethernet.
The Sparx5 switch family consists of following SKUs:
- VSC7546 Sparx5-64
up to 64 Gbps of bandwidth with the following primary port configurations:
- 6 *10G
- 16 * 2.5G + 2 * 10G
- 24 * 1G + 4 * 10G
- VSC7549 Sparx5-90
up to 90 Gbps of bandwidth with the following primary port configurations:
- 9 * 10G
- 16 * 2.5G + 4 * 10G
- 48 * 1G + 4 * 10G
- VSC7552 Sparx5-128
up to 128 Gbps of bandwidth with the following primary port configurations:
- 12 * 10G
- 16 * 2.5G + 8 * 10G
- 48 * 1G + 8 * 10G
- VSC7556 Sparx5-160
up to 160 Gbps of bandwidth with the following primary port configurations:
- 16 * 10G
- 10 * 10G + 2 * 25G
- 16 * 2.5G + 10 * 10G
- 48 * 1G + 10 * 10G
- VSC7558 Sparx5-200
up to 200 Gbps of bandwidth with the following primary port configurations:
- 20 * 10G
- 8 * 25G
In addition, the device supports one 10/100/1000/2500/5000 Mbps SGMII/SerDes
node processor interface (NPI) Ethernet port.
The Sparx5 support is developed on the PCB134 and PCB135 evaluation boards.
- PCB134 main networking features:
- 12x SFP+ front 10G module slots (connected to Sparx5 through SFI).
- 8x SFP28 front 25G module slots (connected to Sparx5 through SFI high speed).
- Optional, one additional 10/100/1000BASE-T (RJ45) Ethernet port
(on-board VSC8211 PHY connected to Sparx5 through SGMII).
- PCB135 main networking features:
- 48x1G (10/100/1000M) RJ45 front ports using 12xVSC8514 QuadPHY’s each
connected to VSC7558 through QSGMII.
- 4x10G (1G/2.5G/5G/10G) RJ45 front ports using the AQR407 10G QuadPHY each
port connects to VSC7558 through SFI.
- 4x SFP28 25G module slots on back connected to VSC7558 through SFI high
speed.
- Optional, one additional 1G (10/100/1000M) RJ45 port using an on-board
VSC8211 PHY, which can be connected to VSC7558 NPI port through SGMII using
a loopback add-on PCB)
This series provides support for:
- SFPs and DAC cables via PHYLINK with a number of 5G, 10G and 25G devices
and media types.
- Port module configuration for 10M to 25G speeds with SGMII, QSGMII,
1000BASEX, 2500BASEX and 10GBASER as appropriate for these modes.
- SerDes configuration via the Sparx5 SerDes driver (see below).
- Host mode providing register based injection and extraction.
- Switch mode providing MAC/VLAN table learning and Layer2 switching offloaded
to the Sparx5 switch.
- STP state, VLAN support, host/bridge port mode, Forwarding DB, and
configuration and statistics via ethtool.
More support will be added at a later stage.

The series depends on the following series currently on their way
into the kernel:
- Sparx5 SerDes Driver
