IPv4/IPv6 Layer 3 (L3) unicast and multicast routing is supported with up to 18K IPv4/9K IPv6 unicast LPM entries and up to 9K IPv4/3K IPv6 (S,G) multicast groups. L3 security features include source guard and reverse path forwarding (uRPF) tasks. Additional L3 features include VRF-Lite and IP tunnels (IP over GRE/IP). The SparX-5 switch family features a highly flexible set of Ethernet ports with support for 10G and 25G aggregation links, QSGMII, USGMII, and USXGMII. The device integrates a powerful 1 GHz dual-core ARM® Cortex®-A53 CPU enabling full management of the switch and advanced Enterprise applications. The SparX-5 switch family targets managed Layer 2 and Layer 3 equipment in SMB, SME, and Enterprise where high port count 1G/2.5G/5G/10G switching with 10G/25G aggregation links is required. The SparX-5 switch family consists of following SKUs: VSC7546 SparX-5-64 supports up to 64 Gbps of bandwidth with the following primary port configurations. - 6 ×10G - 16 × 2.5G + 2 × 10G - 24 × 1G + 4 × 10G VSC7549 SparX-5-90 supports up to 90 Gbps of bandwidth with the following primary port configurations. - 9 × 10G - 16 × 2.5G + 4 × 10G - 48 × 1G + 4 × 10G VSC7552 SparX-5-128 supports up to 128 Gbps of bandwidth with the following primary port configurations. - 12 × 10G - 6 x 10G + 2 x 25G - 16 × 2.5G + 8 × 10G - 48 × 1G + 8 × 10G VSC7556 SparX-5-160 supports 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 SparX-5-200 supports 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. 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 Industrial Ethernet. The Sparx5i support is developed on the PCB134 and PCB135 evaluation boards. - PCB134 main networking features: - 12x SFP+ front 10G module slots (connected to Sparx5i through SFI). - 8x SFP28 front 25G module slots (connected to Sparx5i through SFI high speed). - Optional, one additional 10/100/1000BASE-T (RJ45) Ethernet port (on-board VSC8211 PHY connected to Sparx5i 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 Sparx5i 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 Sparx5i 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 Sparx5i Chip Register Model can be browsed at this location: https://github.com/microchip-ung/sparx-5_reginfo and the datasheet is available here: https://ww1.microchip.com/downloads/en/DeviceDoc/SparX-5_Family_L2L3_Enterprise_10G_Ethernet_Switches_Datasheet_00003822B.pdf The series depends on the following series currently on their way into the kernel: - 25G Base-R phy mode Link: https://lore.kernel.org/r/20210611125453.313308-1-steen.hegelund@microchip.com/ - Sparx5 Reset Driver Link: https://lore.kernel.org/r/20210416084054.2922327-1-steen.hegelund@microchip.com/ ChangeLog: v5: - cover letter - updated the description to match the latest data sheets - basic driver - added error message in case of reset controller error - port struct: replacing has_sfp with inband, adding pause_adv - host mode - port cleanup: unregisters netdevs and then removes phylink etc - checking for pause_adv when comparing port config changes - getting duplex and pause state in the link_up callback. - getting inband, autoneg and pause_adv config in the pcs_config callback. - port - use only the pause_adv bits when getting aneg status - use the inband state when updating the PCS and port config v4: - basic driver: Using devm_reset_control_get_optional_shared to get the reset control, and let the reset framework check if it is valid. - host mode (phylink): Use the PCS operations to get state and update configuration. Removed the setting of interface modes. Let phylink control this. Using the new 5gbase-r and 25gbase-r modes. Using a helper function to check if one of the 3 base-r modes has been selected. Currently it will not be possible to change the interface mode by changing the speed (e.g via ethtool). This will be added later. v3: - basic driver: - removed unneeded braces - release reference to ports node after use - use dev_err_probe to handle DEFER - update error value when bailing out (a few cases) - updated formatting of port struct and grouping of bool values - simplified the spx5_rmw and spx5_inst_rmw inline functions - host mode (netdev): - removed lockless flag - added port timer init - host mode (packet - manual injection): - updated error counters in error situations - implemented timer handling of watermark threshold: stop and restart netif queues. - fixed error message handling (rate limited) - fixed comment style error - used DIV_ROUND_UP macro - removed a debug message for open ports v2: - Updated bindings: - drop minItems for the reg property - Statistics implementation: - Reorganized statistics into ethtool groups: eth-phy, eth-mac, eth-ctrl, rmon as defined by the IEEE 802.3 categories and RFC 2819. - The remaining statistics are provided by the classic ethtool statistics command. - Hostmode support: - Removed netdev renaming - Validate ethernet address in sparx5_set_mac_address() Steen Hegelund (10): dt-bindings: net: sparx5: Add sparx5-switch bindings net: sparx5: add the basic sparx5 driver net: sparx5: add hostmode with phylink support net: sparx5: add port module support net: sparx5: add mactable support net: sparx5: add vlan support net: sparx5: add switching support net: sparx5: add calendar bandwidth allocation support net: sparx5: add ethtool configuration and statistics support arm64: dts: sparx5: Add the Sparx5 switch node .../bindings/net/microchip,sparx5-switch.yaml | 226 + arch/arm64/boot/dts/microchip/sparx5.dtsi | 94 +- .../dts/microchip/sparx5_pcb134_board.dtsi | 481 +- .../dts/microchip/sparx5_pcb135_board.dtsi | 621 ++- drivers/net/ethernet/microchip/Kconfig | 2 + drivers/net/ethernet/microchip/Makefile | 2 + drivers/net/ethernet/microchip/sparx5/Kconfig | 9 + .../net/ethernet/microchip/sparx5/Makefile | 10 + .../microchip/sparx5/sparx5_calendar.c | 596 +++ .../microchip/sparx5/sparx5_ethtool.c | 1227 +++++ .../microchip/sparx5/sparx5_mactable.c | 500 ++ .../ethernet/microchip/sparx5/sparx5_main.c | 852 +++ .../ethernet/microchip/sparx5/sparx5_main.h | 375 ++ .../microchip/sparx5/sparx5_main_regs.h | 4642 +++++++++++++++++ .../ethernet/microchip/sparx5/sparx5_netdev.c | 264 + .../ethernet/microchip/sparx5/sparx5_packet.c | 320 ++ .../microchip/sparx5/sparx5_phylink.c | 210 + .../ethernet/microchip/sparx5/sparx5_port.c | 1146 ++++ .../ethernet/microchip/sparx5/sparx5_port.h | 93 + .../microchip/sparx5/sparx5_switchdev.c | 508 ++ .../ethernet/microchip/sparx5/sparx5_vlan.c | 224 + 21 files changed, 12318 insertions(+), 84 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/microchip,sparx5-switch.yaml create mode 100644 drivers/net/ethernet/microchip/sparx5/Kconfig create mode 100644 drivers/net/ethernet/microchip/sparx5/Makefile create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_calendar.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_ethtool.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_mactable.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_main.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_main.h create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_main_regs.h create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_netdev.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_packet.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_phylink.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_port.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_port.h create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_switchdev.c create mode 100644 drivers/net/ethernet/microchip/sparx5/sparx5_vlan.c
