Reuse tun opts bits in reg c1, to pass IPsec obj id to datapath. As this is only for RX SA and there are only 11 bits, xarray is used to map IPsec obj id to an index, which is between 1 and 0x7ff, and replace obj id to write to reg c1. Signed-off-by:

As decryption must be done first, add new prio for IPsec offload in FDB, and put it just lower than BYPASS prio and higher than TC prio. Three levels are added for RX. The first one is for ip xfrm policy. SA table is created in the second level for ip xfrm state. The status table is created in the last to check the decryption result. If success, packets continue with the next process, or dropped otherwise. For now, the set of reg c1 is removed for swtichdev mode, and the datapath process will be added in the next patch.

As the uplink representor is created only in switchdev mode, add a local variable for IPsec to indicate the device is in this mode. In this mode, IPsec ROCE is disabled, and crypto offload is kept as it is. However, as the tables for packet offload are created in FDB, ipsec->rx_esw and ipsec->tx_esw are added. Signed-off-by:

There is no possible for platform_get_irq() to return 0 and the return value of platform_get_irq() is more sensible to show the error reason. And there is no need to call the dev_warn() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.

Replace bogus comment about matching the latched timestamp to one of the received frames. That comment is probably copied from mv88e6xxx and true for these switches. However, the hellcreek switch is configured to insert the timestamp directly into the PTP packets. While here, remove the other comments regarding the list splicing and locking as well, because it doesn't add any value. Signed-off-by:

MD Danish Anwar says: ==================== Introduce ICSSG based ethernet Driver The Programmable Real-time Unit and Industrial Communication Subsystem Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI SoCs. This subsystem is provided for the use cases like the implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. The subsystem includes many accelerators for data processing like multiplier and multiplier-accumulator. It also has peripherals like UART, MII/RGMII, MDIO, etc. Every ICSSG core includes two 32-bit load/store RISC CPU cores called PRUs. The above features allow it to be used for implementing custom firmware based peripherals like ethernet. This series adds the YAML documentation and the driver with basic EMAC support for TI AM654 Silicon Rev 2 SoC with the PRU_ICSSG Sub-system. running dual-EMAC firmware. This currently supports basic EMAC with 1Gbps and 100Mbps link. 10M and half-duplex modes are not yet supported because they require the support of an IEP, which will be added later. Advanced features like switch-dev and timestamping will be added later. This is the v13 of the patch series [v1]. This version of the patchset addresses comments made on v12. There series doesn't have any dependency. Changes from v12 to v13 : *) Rebased the series on latest net-next. *) Addressed Jakub's comments on ndo_xmit API. Now we will only stop queues based on occupancy not on dma errors. *) Removed limiting the number of serviced packets to budget for Tx NAPI. Now Tx NAPI will keep servicing packets. *) Removed netif_running() check when packet arrives. *) Introduced prototypes of APIs in the same patch where these APIs are added. Dropped __maybe_unused tags as compiler only cares about prototypes existing, not whether actual callers are in place. Now prototypes of these APIs are present in the same patch where they are introduced but thes APIs are called later (in patch 6). Changes from v11 to v12 : *) Rebased the series on latest net-next. *) Addressed Jakub's comments on ndo_xmit API. *) Added hooks to .get_rmon_stats for the driver. Now tx / rx bucket size and frame counts per bucket will be fetched by ethtool_rmon_stats instead of ethtool -S. *) Added __maybe_unused tags to unused config and classifier APIs in patch 2,3 and 4. These tags are later removed in patch 6. Changes from v10 to v11 : *) Rebased the series on latest net-next. *) Split the ICSSG driver introduction patch into 9 different patches as asked by Jakub. *) Introduced new patch(patch 8/10) to dump Standard network interface staticstics via ndo_get_stats64. Now certain stats that are reported by ICSSG hardware and are also part of struct rtnl_link_stats64, will be reported by ndo_get_stats64. While other stats that are not part of the struct rtnl_link_stats64 will be reported by ethtool -S. These stats are not duplicated. Changes from v9 to v10 : *) Rebased the series on latest net-next. *) Moved 'ndev prueth->emac[mac] == emac' assignment to the end of function prueth_netdev_init(). *) In unsupported phy_mode switch case instead of returning -EINVAL, store the error code in ret and 'goto free' Changes from v8 to v9 : *) Rebased the series on latest net-next. *) Fixed smatch and sparse warnings as pointed by Simon. *) Fixed leaky ndev in prueth_netdev_init() as asked by Simon. Changes from v7 to v8 : *) Rebased the series on 6.5-rc1. *) Fixed few formattings. Changes from v6 to v7 : *) Added RB tag of Rob in patch 1 of this series. *) Addressed Simon's comment on patch 2 of the series. *) Rebased patchset on next-20230428 linux-next. Changes from v5 to v6 : *) Added RB tag of Andrew Lunn in patch 2 of this series. *) Addressed Rob's comment on patch 1 of the series. *) Rebased patchset on next-20230421 linux-next. Changes from v4 to v5 : *) Re-arranged properties section in ti,icssg-prueth.yaml file. *) Added requirement for minimum one ethernet port. *) Fixed some minor formatting errors as asked by Krzysztof. *) Dropped SGMII mode from enum mii_mode as SGMII mode is not currently supported by the driver. *) Added switch-case block to handle different phy modes by ICSSG driver. Changes from v3 to v4 : *) Addressed Krzysztof's comments and fixed dt_binding_check errors in patch 1/2. *) Added interrupt-extended property in ethernet-ports properties section. *) Fixed comments in file icssg_switch_map.h according to the Linux coding style in patch 2/2. Added Documentation of structures in patch 2/2. Changes from v2 to v3 : *) Addressed Rob and Krzysztof's comments on patch 1 of this series. Fixed indentation. Removed description and pinctrl section from ti,icssg-prueth.yaml file. *) Addressed Krzysztof, Paolo, Randy, Andrew and Christophe's comments on patch 2 of this seires. *) Fixed blanklines in Kconfig and Makefile. Changed structures to const as suggested by Krzysztof. *) Fixed while loop logic in emac_tx_complete_packets() API as suggested by Paolo. Previously in the loop's last iteration 'budget' was 0 and napi_consume_skb would wrongly assume the caller is not in NAPI context Now, budget won't be zero in last iteration of loop. *) Removed inline functions addr_to_da1() and addr_to_da0() as asked by Andrew. *) Added dev_err_probe() instead of dev_err() as suggested by Christophe. *) In ti,icssg-prueth.yaml file, in the patternProperties section of ethernet-ports, kept the port name as "port" instead of "ethernet-port" as all other drivers were using "port". Will change it if is compulsory to use "ethernet-port". ==================== Signed-off-by: -

Add icssg_stats.c to help dump, icssg related driver statistics. ICSSG has hardware registers for providing statistics like total rx bytes, total tx bytes, etc. These registers are of 32 bits and hence in case of 1G link, they overflows in around 32 seconds. The behaviour of these registers is such that they don't roll back to 0 after overflow but rather stay at UINT_MAX. These registers support a feature where the value written to them is subtracted from the register. This feature can be utilized to fix the overflowing of stats. This solution uses a Workqueues based solution where a function gets called before the registers overflow (every 25 seconds in 1G link, 25000 seconds in 100M link), this function saves the register values in local variables and writes the last read value to the register. So any update during the read will be taken care of. Signed-off-by:

This is the Ethernet driver for TI AM654 Silicon rev. 2 with the ICSSG PRU Sub-system running dual-EMAC firmware. The Programmable Real-time Unit and Industrial Communication Subsystem Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI SoCs. This subsystem is provided for the use cases like implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. Every ICSSG core has two Programmable Real-Time Unit(PRUs), two auxiliary Real-Time Transfer Unit (RT_PRUs), and two Transmit Real-Time Transfer Units (TX_PRUs). Each one of these runs its own firmware. Every ICSSG core has two MII ports connect to these PRUs and also a MDIO port. The cores can run different firmwares to support different protocols and features like switch-dev, timestamping, etc. It uses System DMA to transfer and receive packets and shared memory register emulation between the firmware and driver for control and configuration. This patch adds support for basic EMAC functionality with 1Gbps and 100Mbps link speed. 10M and half duplex mode are not supported currently as they require IEP, the support for which will be added later. Support for switch-dev, timestamp, etc. will be added later by subsequent patch series. Signed-off-by:

Neil Armstrong says: ==================== net: ethernet: dwmac: oxnas glue removal With [1] removing MPCore SMP support, this makes the OX820 barely usable, associated with a clear lack of maintainance, development and migration to dt-schema it's clear that Linux support for OX810 and OX820 should be removed. In addition, the OX810 hasn't been booted for years and isn't even present in an ARM config file. For the OX820, lack of USB and SATA support makes the platform not usable in the current Linux support and relies on off-tree drivers hacked from the vendor (defunct for years) sources. The last users are in the OpenWRT distribution, and today's removal means support will still be in stable 6.1 LTS kernel until end of 2026. If someone wants to take over the development even with lack of SMP, I'll be happy to hand off maintainance. It has been a fun time adding support for this architecture, but it's time to get over!

Petr Machata says: ==================== selftests: New selftests for out-of-order-operations patches in mlxsw In the past, the mlxsw driver made the assumption that the user applies configuration in a bottom-up manner. Thus netdevices needed to be added to the bridge before IP addresses were configured on that bridge or SVI added on top of it, because whatever happened before a netdevice was mlxsw upper was generally ignored by mlxsw. Recently, several patch series were pushed to introduce the bookkeeping and replays necessary to offload the full state, not just the immediate configuration step. In this patchset, introduce new selftests that directly exercise the out of order code paths in mlxsw. - Patch #1 adds new tests into the existing selftest router_bridge.sh. - Patches #2-#5 add new generic selftests. - Patches #6-#8 add new mlxsw-specific selftests. ==================== Signed-off-by: -
