Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-05-02 This series contains updates to the ice driver only. Anirudh introduces the framework to store queue specific information in the VSI queue contexts. This will allow future changes to update the structure to hold queue specific information. Akeem adds additional check so that if there is no queue to disable when attempting to disable a queue, return a configuration error without acquiring the lock. Fixed an issue with non-trusted VFs being able to add more than the permitted number of VLANs. Bruce removes unreachable code and updated the function to return void since it would never return anything but success. Brett provides most of the changes in the series, starting with reducing the scope of the error variable used and improved the debug message if we fail to configure the receive queue. Updates the driver to use a macro instead of using the same 'for' loop throughout the driver which helps with readability. Fixed an issue where users were led to believe they could set rx-usecs-high value, yet the changes to this value would not stick because it was not yet implemented to allow changes to this value, so implement the missing code to change the value. Found we had unnecessary wait when disabling queues, so remove it. I,proved a wasteful addition operation in our hot path by adding a member to the ice_q_vector structure and the necessary changes to use the member which stores the calculated vector hardware index. Refactored the link event flow to make it cleaner and more clear. Maciej updates the array index when stopping transmit rings, so that process every ring the VSI, not just the rings in a given transmit class. Paul adds support for setting 52 byte RSS hash keys. Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register, since the interrupt handlers will handle resetting the bit, if necessary. Tony adds a missing PHY type, which was causing warning message about an unrecognized PHY. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(*tx_msg) + le16_to_cpu(tx_msg->num_pls) * sizeof(tx_msg->pld[0]); with: struct_size(tx_msg, pld, le16_to_cpu(tx_msg->num_pls)); This code was detected with the help of Coccinelle.

Previously, our driver only supports phydev to autoneg or change port speed. This patch adds support for fibre port, driver gets media speed capability and autoneg capability from firmware. If the media supports multiple speeds, user can change port speed with command "ethtool -s <devname> speed xxxx autoneg off duplex full". If autoneg on, the user configuration may be overwritten by the autoneg result. Signed-off-by:

Previously, we can only identify copper and fiber type, the supported link modes of port information are always showing SR type. This patch adds support for multiple media types, include SR, LR CR, KR. Driver needs to query the media type from firmware periodicly, and updates the port information. The new port information looks like this: Settings for eth0: Supported ports: [ FIBRE ] Supported link modes: 25000baseCR/Full 25000baseSR/Full 1000baseX/Full 10000baseCR/Full 10000baseSR/Full 10000baseLR/Full Supported pause frame use: Symmetric Supports auto-negotiation: No Supported FEC modes: None BaseR Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: Not reported Speed: 10000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: off Current message level: 0x00000036 (54) probe link ifdown ifup Link detected: yes In order to be compatible with old firmware which only support sfp speed, we remained using the same query command, and kept the former logic.

ipheth_carrier_set() is called from two locations. In ipheth_carrier_check_work(), its parameter 'dev' is set with container_of(work, ...) and can not be NULL. In ipheth_open(), dev is extracted from netdev_priv(net) and dereferenced before the call to ipheth_carrier_set(). The NULL pointer check of dev in ipheth_carrier_set() is therefore unnecessary and can be removed. Cc: Gustavo A. R. Silva <garsilva@embeddedor.com> Signed-off-by:

If the NO_CPU strap is set, the switch starts in 'dumb hub' mode, with all ports enable. Ports which are then actively used are reconfigured as required when the driver starts. However unused ports are left alone. Change this to disable them, and turn off any SERDES interface. This could save some power and so reduce the temperature a bit. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2019-05-03 This series contains updates to the i40e driver only. Carolyn changes the driver behavior to now disable the VF after one MDD event instead of allowing a couple of MDD events before doing the reset. Aleksandr changes the driver to only report an error when a VF tries to remove VLAN when a port VLAN is configured, unless it is VLAN 0. Also extends the LLDP support to be able to keep the current LLDP state persistent across a power cycle. Maciej fixes the checksum calculation due to firmware changes, which requires the driver to perform a double shadow RAM dump in some cases. Adam adds advertising support for 40GBase_LR4, 40GBase_CR4 and fibre in the driver. Jake cleans up a check that is not needed and was producing a warning in GCC 8. Harshitha fixes a misleading message by ensuring that a success message is only printed on the host side when the promiscuous mode change has been successful. Stefan Assmann adds the vendor id and device id to the dmesg log entry during probe to help with bug reports when lspci output may not be available.

This patch introduces "recovery mode" to the i40e driver. It is part of a new Any2Any idea of upgrading the firmware. In this approach, it is required for the driver to have support for "transition firmware", that is used for migrating from structured to flat firmware image. In this new, very basic mode, i40e driver must be able to handle particular IOCTL calls from the NVM Update Tool and run a small set of AQ commands. These additional AQ commands are part of the interface used by the NVMUpdate tool. The NVMUpdate tool contains all of the necessary logic to reference these new AQ commands. The end user experience remains the same, they are using the NVMUpdate tool to update the NVM contents. Signed-off-by:

A refactor of the i40e_vc_config_promiscuous_mode_msg function moved the check for un-trusted VF into another function. We have to lie to an un-trusted VF that its request to set promiscuous mode is successful even when it is not because we don't want the VF to find out its trust status this way. With the refactor, we were running into a case where even though we were not setting promiscuous mode for an un-trusted VF, we still printed a misleading message that it was successful. This patch fixes that by ensuring that a success message is printed on the host side only when the promiscuous mode change has been successful. Signed-off-by:

The function i40e_validate_cloud_filter checks that the destination and source port numbers are valid by attempting to ensure that the number is non-zero and no larger than 0xFFFF. However, the types for the dst_port and src_port variable are __be16 which by definition cannot be larger than 0xFFFF Since these values cannot be larger than 2 bytes, the check to see if they exceed 0xFFFF is meaningless. One might consider these checks as some sort of defensive coding, in case the type was later changed. However, these checks also byte-swap the value before comparison using be16_to_cpu, which will truncate the values to 16bits anyways. Additionally, changing the type would require updating the opcodes to support new data layout of these virtchnl commands. Remove the check to silence the -Wtype-limits warning that was added to GCC 8. Signed-off-by:

Vladimir Oltean says: ==================== NXP SJA1105 DSA driver This patchset adds a DSA driver for the SPI-controlled NXP SJA1105 switch. Due to the hardware's unfriendliness, most of its state needs to be shadowed in kernel memory by the driver. To support this and keep a decent amount of cleanliness in the code, a new generic API for converting between CPU-accessible ("unpacked") structures and hardware-accessible ("packed") structures is proposed and used. The driver is GPL-2.0 licensed. The source code files which are licensed as BSD-3-Clause are hardware support files and derivative of the userspace NXP sja1105-tool program, which is BSD-3-Clause licensed. TODO items: * Add support for traffic. * Add full support for the P/Q/R/S series. The patches were mostly tested on a first-generation T device. * Add timestamping support and PTP clock manipulation. * Figure out how the tc-taprio hardware offload that was just proposed by Vinicius can be used to configure the switch's time-aware scheduler. * Rework link state callbacks to use phylink once the SGMII port is supported. Changes in v5: 1. Removed trailing empty lines at the end of files. 2. Moved the lib/packing.c file under a CONFIG_PACKING option instead of having it always built-in. The module is GPL licensed, which applies to its distribution in binary form, but the code is dual-licensed which means it can be used in projects with other licenses as well. 3. Made SJA1105 driver select CONFIG_PACKING and CONFIG_CRC32. v4 patchset can be found at: https://lwn.net/Articles/787077/ Changes in v4: 1. Previous patchset was broken apart, and for the moment the driver is configuring the switch as unmanaged. Support for regular and management traffic, as well as for PTP timestamping, will be submitted once the basic driver is accepted. Some core DSA patches were also broken out of the series, and are a dependency for this series: https://patchwork.ozlabs.org/project/netdev/list/?series=105069 2. Addressed Jiri Pirko's feedback about too generic function and macro naming. 3. Re-introduced ETH_P_DSA_8021Q. v3 patchset can be found at: https://lkml.org/lkml/2019/4/12/978 Changes in v3: 1. Removed the patch for a dedicated Ethertype to use with 802.1Q DSA tagging 2. Changed the SJA1105 switch tagging protocol sysfs label from "sja1105" to "8021q" to denote to users such as tcpdump that the structure is more generic. 3. Respun previous patch "net: dsa: Allow drivers to modulate between presence and absence of tagging". Current equivalent patch is called "net: dsa: Allow drivers to filter packets they can decode source port from" and at least allows reception of management traffic during the time when switch tagging is not enabled. 4. Added DSA-level fixes for the bridge core not unsetting vlan_filtering when ports leave. The global VLAN filtering is treated as a special case. Made the mt7530 driver use this. This patch benefits the SJA1105 because otherwise traffic in standalone mode would no longer work after removing the ports from a vlan_filtering bridge, since the driver and the hardware would be in an inconsistent state. 5. Restructured the documentation as rst. This depends upon the recently submitted "[PATCH net-next] Documentation: net: dsa: transition to the rst format": https://patchwork.ozlabs.org/patch/1084658/. v2 patchset can be found at: https://www.spinics.net/lists/netdev/msg563454.html Changes in v2: 1. Device ID is no longer auto-detected but enforced based on explicit DT compatible string. This helps with stricter checking of DT bindings. 2. Group all device-specific operations into a sja1105_info structure and avoid using the IS_ET() and IS_PQRS() macros at runtime as much as possible. 3. Added more verbiage to commit messages and documentation. 4. Treat the case where RGMII internal delays are requested through DT bindings and return error. 5. Miscellaneous cosmetic cleanup in sja1105_clocking.c 6. Not advertising link features that are not supported, such as pause frames and the half duplex modes. 7. Fixed a mistake in previous patchset where the switch tagging was not actually enabled (lost during a rebase). This brought up another uncaught issue where switching at runtime between tagging and no-tagging was not supported by DSA. Fixed up the mistake in "net: dsa: sja1105: Add support for traffic through standalone ports", and added the new patch "net: dsa: Allow drivers to modulate between presence and absence of tagging" to address the other issue. 8. Added a workaround for switch resets cutting a frame in the middle of transmission, which would throw off some link partners. 9. Changed the TPID from ETH_P_EDSA (0xDADA) to a newly introduced one: ETH_P_DSA_8021Q (0xDADB). Uncovered another mistake in the previous patchset with a missing ntohs(), which was not caught because 0xDADA is endian-agnostic. 10. Made NET_DSA_TAG_8021Q select VLAN_8021Q 11. Renamed __dsa_port_vlan_add to dsa_port_vid_add and not to dsa_port_vlan_add_trans, as suggested, because the corresponding _del function does not have a transactional phase and the naming is more uniform this way. v1 patchset can be found at: https://www.spinics.net/lists/netdev/msg561589.html Changes from RFC: 1. Removed the packing code for the static configuration tables that were not currently used 2. Removed the code for unpacking a static configuration structure from a memory buffer (not used) 3. Completely removed the SGMII stubs, since the configuration is not complete anyway. 4. Moved some code from the SJA1105 introduction commit into the patch that used it. 5. Made the code for checking global VLAN filtering generic and made b53 driver use it. 6. Made mt7530 driver use the new generic dp->vlan_filtering 7. Fixed check for stringset in .get_sset_count 8. Minor cleanup in sja1105_clocking.c 9. Fixed a confusing typo in DSA RFC can be found at: https://www.mail-archive.com/netdev@vger.kernel.org/msg291717.html ==================== Signed-off-by: -

Ethernet flow control: The switch MAC does not consume, nor does it emit pause frames. It simply forwards them as any other Ethernet frame (and since the DMAC is, per IEEE spec, 01-80-C2-00-00-01, it means they are filtered as link-local traffic and forwarded to the CPU, which can't do anything useful with them). Duplex: There is no duplex setting in the SJA1105 MAC. It is known to forward traffic at line rate on the same port in both directions. Therefore it must be that it only supports full duplex.

Resetting the switch at runtime is currently done while changing the vlan_filtering setting (due to the required TPID change). But reset is asynchronous with packet egress, and the switch core will not wait for egress to finish before carrying on with the reset operation. As a result, a connected PHY such as the BCM5464 would see an unterminated Ethernet frame and start to jabber (repeat the last seen Ethernet symbols - jabber is by definition an oversized Ethernet frame with bad FCS). This behavior is strange in itself, but it also causes the MACs of some link partners (such as the FRDM-LS1012A) to completely lock up. So as a remedy for this situation, when switch reset is required, simply inhibit Tx on all ports, and wait for the necessary time for the eventual one frame left in the egress queue (not even the Tx inhibit command is instantaneous) to be flushed.

If STP is active, this setting is applied on bridged ports each time an Ethernet link is established (topology changes). Since the setting is global to the switch and a reset is required to change it, resets are prevented if the new callback does not change the value that the hardware already is programmed for.

VLAN filtering cannot be properly disabled in SJA1105. So in order to emulate the "no VLAN awareness" behavior (not dropping traffic that is tagged with a VID that isn't configured on the port), we need to hack another switch feature: programmable TPID (which is 0x8100 for 802.1Q). We are reprogramming the TPID to a bogus value which leaves the switch thinking that all traffic is untagged, and therefore accepts it. Under a vlan_filtering bridge, the proper TPID of ETH_P_8021Q is installed again, and the switch starts identifying 802.1Q-tagged traffic. Signed-off-by:

There are two possible utilizations so far: - Switch devices that don't support a native insertion/extraction header on the CPU port may still enjoy the benefits of port isolation with a custom VLAN tag. For this, they need to have a customizable TPID in hardware and a new Ethertype to distinguish between real 802.1Q traffic and the private tags used for port separation. - Switches that don't support the deactivation of VLAN awareness, but still want to have a mode in which they accept all traffic, including frames that are tagged with a VLAN not configured on their ports, may use this as a fake to trick the hardware into thinking that the TPID for VLAN is something other than 0x8100. What follows after the ETH_P_DSA_8021Q EtherType is a regular VLAN header (TCI), however there is no other EtherType that can be used for this purpose and doesn't already have a well-defined meaning. ETH_P_8021AD, ETH_P_QINQ1, ETH_P_QINQ2 and ETH_P_QINQ3 expect that another follow-up VLAN tag is present, which is not the case here. Signed-off-by:

Documentation/devicetree/bindings/net/ethernet.txt is confusing because it says what the MAC should not do, but not what it *should* do: * "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC should not add an RX delay in this case) The gap in semantics is threefold: 1. Is it illegal for the MAC to apply the Rx internal delay by itself, and simplify the phy_mode (mask off "rgmii-rxid" into "rgmii") before passing it to of_phy_connect? The documentation would suggest yes. 1. For "rgmii-rxid", while the situation with the Rx clock skew is more or less clear (needs to be added by the PHY), what should the MAC driver do about the Tx delays? Is it an implicit wild card for the MAC to apply delays in the Tx direction if it can? What if those were already added as serpentine PCB traces, how could that be made more obvious through DT bindings so that the MAC doesn't attempt to add them twice and again potentially break the link? 3. If the interface is a fixed-link and therefore the PHY object is fixed (a purely software entity that obviously cannot add clock skew), what is the meaning of the above property? So an interpretation of the RGMII bindings was chosen that hopefully does not contradict their intention but also makes them more applied. The SJA1105 driver understands to act upon "rgmii-*id" phy-mode bindings if the port is in the PHY role (either explicitly, or if it is a fixed-link). Otherwise it always passes the duty of setting up delays to the PHY driver. The error behavior that this patch adds is required on SJA1105E/T where the MAC really cannot apply internal delays. If the other end of the fixed-link cannot apply RGMII delays either (this would be specified through its own DT bindings), then the situation requires PCB delays. For SJA1105P/Q/R/S, this is however hardware supported and the error is thus only temporary. I created a stub function pointer for configuring delays per-port on RXC and TXC, and will implement it when I have access to a board with this hardware setup. Meanwhile do not allow the user to select an invalid configuration. Signed-off-by: -

Currently only the (more difficult) first generation E/T series is supported. Here the TCAM is only 4-way associative, and to know where the hardware will search for a FDB entry, we need to perform the same hash algorithm in order to install the entry in the correct bin. On P/Q/R/S, the TCAM should be fully associative. However the SPI command interface is different, and because I don't have access to a new-generation device at the moment, support for it is TODO.

This structure was used intensively for machine specific values when DT was not used. Since the removal of AVR32 from the kernel, this structure is only used for passing clocks from PCI macb wrapper, all other fields being 0. All other known platforms use DT. Remove the leftovers but make sure that PCI macb still works as expected by using default values: - phydev->irq is set to PHY_POLL by mdiobus_alloc() - mii_bus->phy_mask is cleared while allocating it - bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found in DT. This simplifies driver probe path and particularly phy handling. Signed-off-by:
