Add XDP support to the IGB driver. The implementation follows the IXGBE XDP implementation closely and I used the following patches as basis: 1. commit 92470808 ("ixgbe: add XDP support for pass and drop actions") 2. commit 33fdc82f ("ixgbe: add support for XDP_TX action") 3. commit ed93a398 ("ixgbe: tweak page counting for XDP_REDIRECT") Due to the hardware constraints of the devices using the IGB driver we must share the TX queues with XDP which means locking the TX queue for XDP. I ran tests on an older device to get better numbers. Test machine: Intel(R) Atom(TM) CPU C2338 @ 1.74GHz (2 Cores) 2x Intel I211 Routing Original Driver Network Stack: 382 Kpps Routing XDP Redirect (xdp_fwd_kern): 1.48 Mpps XDP Drop: 1.48 Mpps Using XDP we can achieve line rate forwarding even on an older Intel Atom CPU.

Jakub Kicinski says: ==================== udp_tunnel: convert Intel drivers with shared tables This set converts Intel drivers which have the ability to spawn multiple netdevs, but have only one UDP tunnel port table. Appropriate support is added to the core infra in patch 1, followed by netdevsim support and a selftest. The table sharing works by core attaching the same table structure to all devices sharing the table. This means the reference count has to accommodate potentially large values. Once core is ready i40e and ice are converted. These are complex drivers, but we got a tested-by from Aaron, so we should be good :) Compared to v1 I've made sure the selftest is executable. Other than that patches 8 and 9 are actually from the Mellanox conversion series were kept out to avoid Mellanox vs Intel conflicts. Last patch is new, some docs to let users knows ethtool can now display UDP tunnel info. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Convert ice to the new infra, use share port tables. Leave a tiny bit more error checking in place than usual, because this driver really does quite a bit of magic. We need to calculate the number of VxLAN and GENEVE entries the firmware has reserved. Thanks to the conversion the driver will no longer sleep in an atomic section. Signed-off-by:

Make use of the "shared port table" to convert i40e to the new infra. i40e did not have any reference tracking, locking is also dodgy because rtnl gets released while talking to FW, so port may get removed from the table while it's getting added etc. On the good side i40e does not seem to be using the ports for TX so we can remove the table from the driver state completely.

We should never see a removal of a port which is not in the table or adding a port to an occupied entry in the table. To make sure such errors don't escape the checks in the test script add a warning/kernel spat. Error injection will not trigger those, nor should it ever put us in a bad state. Signed-off-by:

Unfortunately recent Intel NIC designs share the UDP port table across netdevs. So far the UDP tunnel port state was maintained per netdev, we need to extend that to cater to Intel NICs. Expect NICs to allocate the info structure dynamically and link to the state from there. All the shared NICs will record port offload information in the one instance of the table so we need to make sure that the use count can accommodate larger numbers. Signed-off-by:

Dan Murphy says: ==================== DP83869 WoL and Speed optimization Add the WoL and Speed Optimization (aka downshift) support for the DP83869 Ethernet PHY. ==================== Signed-off-by: -
Dan Murphy authored
Set the speed optimization bit on the DP83869 PHY. Speed optimization, also known as link downshift, enables fallback to 100M operation after multiple consecutive failed attempts at Gigabit link establishment. Such a case could occur if cabling with only four wires (two twisted pairs) were connected instead of the standard cabling with eight wires (four twisted pairs). The number of failed link attempts before falling back to 100M operation is configurable. By default, four failed link attempts are required before falling back to 100M. Signed-off-by:

Michael Chan says: ==================== bnxt_en: Update for net-next. This patch series adds 2 main features to the bnxt_en driver: 200G link speed support and FEC support with some refactoring of the link speed logic. The firmware interface is updated to have proper support for these 2 features. The ethtool preset max channel value is also adjusted properly to account for XDP and TCs. ==================== Signed-off-by: -
Michael Chan authored
The current logic that calculates the preset maximum value for combined channel does not take into account the rings used for XDP and mqprio TCs. Each of these features will reduce the number of TX rings. Add the logic to divide the TX rings accordingly based on whether the device is currently in XDP mode and whether TCs are in use.

PORT_PHY_CONFIG is always sent with REQ_FLAGS_RESET_PHY set. This flag must be set in order for the firmware to institute the requested PHY change immediately, but it results in a link flap. This is unnecessary and results in an improved user experience if the PHY reconfiguration is avoided when the user requested speed does not constitute a change. Signed-off-by:

On some 200G dual port NICs, if one port is configured to 200G, firmware will disable the ethernet link on the other port. Firmware will send notification to the driver for the disabled port when this happens. Define a new field in the link_info structure to keep track of this state. The new phy_state field replaces the unused loop_back field. Log a message when the phy_state changes state. In the disabled state, disallow any PHY configurations on the disabled port as the firmware will fail all calls to configure the PHY in this state. Reviewed-by:

The firmware interface has added support for new link speeds using PAM4 modulation. Expand the bnxt_link_info structure to closely mirror the new firmware structures. Add logic to copy the PAM4 capabilities and settings from the firmware. Signed-off-by:
-
Edwin Peer authored
It will be necessary to update more than one field in the link_info structure when PAM4 speeds are added in a later patch. Instead of merely translating ethtool speed values to firmware speed values, change the responsiblity of this function to update all the necessary link_info fields required to force the speed change to the desired ethtool value. This also reduces code duplication somewhat at the two call sites, which otherwise both have to independently update link_info fields to turn off auto negotiation advertisements. Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen to have the same values, but req_link_speed is utilimately passed as force_link_speed in HWRM_PORT_PHY_CFG which is not defined in terms of REQ_AUTO_LINK_SPEED. Reviewed-by:

Extract the code for determining an advertised speed is no longer supported into a separate function. This will avoid some code duplication in a later patch when supporting PAM4 speeds, since these speeds are specified in a separate field. Reviewed-by:

The main changes include FEC, ECN statistics, HWRM_PORT_PHY_QCFG response size reduction, and a new counter added to ctx_hw_stats_ext struct to support the new 58818 chip. The ctx_hw_stats_ext structure is now the superset supporting the new 58818 chips and the prior P5 chips. Add a new flag to identify the new chip and use constants for the chip specific ring statistics sizes instead of the size of the structure. Because the HWRM_PORT_PHY_QCFG response structure size has shrunk back to 96 bytes, the workaround added earlier to limit the size of this message for forwarding to the VF can be removed.

Ido Schimmel says: ==================== mlxsw: Expose transceiver overheat counter Amit says: An overheated transceiver can be the root cause of various network problems such as link flapping. Counting the number of times a transceiver's temperature was higher than its configured threshold can therefore help in debugging such issues. This patch set exposes a transceiver overheat counter via ethtool. This is achieved by configuring the Spectrum ASIC to generate events whenever a transceiver is overheated. The temperature thresholds are queried from the transceiver (if available) and set to the default otherwise. Example: ... transceiver_overheat: 2 Patch set overview: Patches #1-#3 add required device registers Patches #4-#5 add required infrastructure in mlxsw to configure and count overheat events Patches #6-#9 gradually add support for the transceiver overheat counter Patch #10 exposes the transceiver overheat counter via ethtool ==================== Signed-off-by: -

Module temperature warning events are enabled for modules that have a temperature sensor and configured according to the temperature thresholds queried from the module. When a module is unplugged we are guaranteed not to get temperature warning events. However, when a module is plugged in we need to potentially update its current settings (i.e., event enablement and thresholds). Register to port module plug/unplug events and update module's settings upon plug in events. Signed-off-by:

The overheat counter is a per-module counter, but it is exposed as part of the corresponding netdev's statistics. It should therefore be presented to user space relative to the netdev's lifetime. Query the counter just before registering the netdev, so that the value exposed to user space will be relative to this initial value. Signed-off-by:
