On some hardware LEDs would not blink after command 'ethtool -p {eth-port}' in certain circumstances. Now, function does not care about the activity of the LED (though still preserves its state) but forcibly executes identification blinking and then restores the LED state.

In the case where PTP is running on the hardware clock, but the kernel system time is not being synced, a device reset can mess up the clock time. This occurs because we reset the clock time based on the kernel time every reset. This causes us to potentially completely reset the PTP time, and can cause unexpected behavior in programs like ptp4l. Avoid this by saving the PTP time prior to device reset, and then restoring using that time after the reset. Directly restoring the PTP time we saved isn't perfect, because time should have continued running, but the clock will essentially be stopped during the reset. This is still better than the current solution of assuming that the PTP HW clock is synced to the CLOCK_REALTIME. We can do even better, by saving the ktime and calculating a differential, using ktime_get(). This is based on CLOCK_MONOTONIC, and allows us to get a fairly precise measure of the time difference between saving and restoring the time. Using this, we can update the saved PTP time, and use that as the value to write to the hardware clock registers. This, of course is not perfect. However, it does help ensure that the PTP time is restored as close as feasible to the time it should have been if the reset had not occurred. During device initialization, continue using the system time as the source for the creation of the PTP clock, since this is the best known current time source at driver load. Signed-off-by:

This patch introduces DDP (Dynamic Device Personalization) which allows loading profiles that change the way internal parser interprets processed frames. To load DDP profiles it utilizes ethtool flash feature. The files with recipes must be located in /var/lib/firmware directory. Afterwards the recipe can be loaded by invoking: ethtool -f <if_name> <file_name> 100 ethtool -f <if_name> - 100 See further details of this feature in the i40e documentation, or visit https://www.intel.com/content/www/us/en/architecture-and-technology/ethernet/dynamic-device-personalization-brief.html The driver shall verify DDP profile can be loaded in accordance with the rules: * Package with Group ID 0 are exclusive and can only be loaded the first. * Packages with Group ID 0x01-0xFE can only be loaded simultaneously with the packages from the same group. * Packages with Group ID 0xFF are compatible with all other packages.

Added a new local variable in the i40e_setup_tc function named old_queue_pairs so num_queue_pairs can be restored to the correct value in case configuring queue channels fails. Additionally, moved the exit label in the i40e_setup_tc function so the if (need_reset) block can be executed. Also, fixed data packing in the i40e_setup_tc function. Signed-off-by:

Recently genphy_read_abilities() has been added that dynamically detects clause 22 PHY abilities. I *think* this detection should work with all supported PHY's, at least for the ones with basic features sets, i.e. PHY_BASIC_FEATURES and PHY_GBIT_FEATURES. So let's remove setting these features explicitly and rely on phylib feature detection. I don't have access to most of these PHY's, therefore I'd appreciate regression testing. v2: - make the feature constant a comment so that readers know which features are supported by the respective PHY Signed-off-by:

Simon Horman says: ==================== nfp: Flower flow merging John Hurley says, These patches deal with 'implicit recirculation' on the NFP. This is a firmware feature whereby a packet egresses to an 'internal' port meaning that it will recirculate back to the header extract phase with the 'internal' port now marked as its ingress port. This internal port can then be matched on by another rule. This process simulates how OvS datapath outputs to an internal port. The FW traces the packet's recirculation route and sends a 'merge hint' to the driver telling it which flows it matched against. The driver can then decide if these flows can be merged to a single rule and offloaded. The patches deal with the following issues: - assigning/freeing IDs to/from each of these new internal ports - offloading rules that match on internal ports - offloading neighbour table entries whose egress port is internal - handling fallback traffic with an internal port as ingress - using merge hints to create 'faster path' flows and tracking stats etc. ==================== Signed-off-by: -

A merge flow is formed from 2 sub flows. The match fields of the merge are the same as the first sub flow that has formed it, with the actions being a combination of the first and second sub flow. Therefore, a merge flow should replace sub flow 1 when offloaded. Offload valid merge flows by using a new 'flow mod' message type to replace an existing offloaded rule. Track the deletion of sub flows that are linked to a merge flow and revert offloaded merge rules if required. Signed-off-by:

With the merging of 2 sub flows, a new 'merge' flow will be created and written to FW. The TC layer is unaware that the merge flow exists and will request stats from the sub flows. Conversely, the FW treats a merge rule the same as any other rule and sends stats updates to the NFP driver. Add links between merge flows and their sub flows. Use these links to pass merge flow stats updates from FW to the underlying sub flows, ensuring TC stats requests are handled correctly. The updating of sub flow stats is done on (the less time critcal) TC stats requests rather than on FW stats update. Signed-off-by:

When combining 2 sub_flows to a single 'merge flow' (assuming the merge is valid), the merge flow should contain the same match fields as sub_flow 1 with actions derived from a combination of sub_flows 1 and 2. This action list should have all actions from sub_flow 1 with the exception of the output action that triggered the 'implicit recirculation' by sending to an internal port, followed by all actions of sub_flow 2. Any pre-actions in either sub_flow should feature at the start of the action list. Add code to generate a new merge flow and populate the match and actions fields based on the sub_flows. The offloading of the flow is left to future patches. Signed-off-by:

Two flows can be merged if the second flow (after recirculation) matches on bits that are either matched on or explicitly set by the first flow. This means that if a packet hits flow 1 and recirculates then it is guaranteed to hit flow 2. Add a 'can_merge' function that determines if 2 sub_flows in a merge hint can be validly merged to a single flow. Signed-off-by:

If a merge hint is received containing 2 flows that are matched via an implicit recirculation (sending to and matching on an internal port), fw reports that the flows (called sub_flows) may be able to be combined to a single flow. Add infastructure to accept and process merge hint messages. The actual merging of the flows is left as a stub call. Signed-off-by:

Each flow is given a context ID that the fw uses (along with its cookie) to identity the flow. The flows stats are updated by the fw via this ID which is a reference to a pre-allocated array entry. In preparation for flow merge code, enable the nfp_fl_payload structure to be accessed via this stats context ID. Rather than increasing the memory requirements of the pre-allocated array, add a new rhashtable to associate each active stats context ID with its rule payload. While adding new code to the compile metadata functions, slightly restructure the existing function to allow for cleaner, easier to read error handling. Signed-off-by:

The neighbour table in the FW only accepts next hop entries if the egress port is an nfp repr. Modify this to allow the next hop to be an internal port. This means that if a packet is to egress to that port, it will recirculate back into the system with the internal port becoming its ingress port. Signed-off-by:

FW may receive a packet with its ingress port marked as an internal port. If a rule does not exist to match on this port, the packet will be sent to the NFP driver. Modify the flower app to detect packets from such internal ports and convert the ingress port to the correct kernel space netdev. At this point, it is assumed that fallback packets from internal ports are to be sent out said port. Therefore, set the redir_egress bool to true on detection of these ports. Signed-off-by:

John Hurley authored
Currently, it is assumed that fallback packets will be from reprs. Modify this to allow an app to receive non-repr ports from the fallback channel - e.g. from an internal port. If such a packet is received, do not update repr stats. Change the naming function calls so as not to imply it will always be a repr netdev returned. Add the option to set a bool value to redirect a fallback packet out the returned port rather than RXing it. Setting of this bool in subsequent patches allows the handling of packets falling back when they are due to egress an internal port. Signed-off-by:

Recent FW modifications allow the offloading of non repr ports. These ports exist internally on the NFP. So if a rule outputs to an 'internal' port, then the packet will recirculate back into the system but will now have this internal port as it's incoming port. These ports are indicated by a specific type field combined with an 8 bit port id. Add private app data to assign additional port ids for use in offloads. Provide functions to lookup or create new ids when a rule attempts to match on an internal netdev - the only internal netdevs currently supported are of type openvswitch. Have a netdev notifier to release port ids on netdev unregister. OvS offloads rules that match on internal ports as TC egress filters. Ensure that such rules are accepted by the driver.

Write to a FW symbol to indicate that the driver supports flow merging. If this symbol does not exist then flow merging and recirculation is not supported on the FW. If support is available, add a stub to deal with FW to kernel merge hint messages. Full flow merging requires the firmware to support of flow mods. If it does not, then do not attempt to 'turn on' flow merging. Signed-off-by:

sk_forward_alloc's updating is also done on rx path, but to be consistent we change to use sk_mem_charge() in sctp_skb_set_owner_r(). In sctp_eat_data(), it's not enough to check sctp_memory_pressure only, which doesn't work for mem_cgroup_sockets_enabled, so we change to use sk_under_memory_pressure(). When it's under memory pressure, sk_mem_reclaim() and sk_rmem_schedule() should be called on both RENEGE or CHUNK DELIVERY path exit the memory pressure status as soon as possible. Note that sk_rmem_schedule() is using datalen to make things easy there. Reported-by:

Now when sending packets, sk_mem_charge() and sk_mem_uncharge() have been used to set sk_forward_alloc. We just need to call sk_wmem_schedule() to check if the allocated should be raised, and call sk_mem_reclaim() to check if the allocated should be reduced when it's under memory pressure. If sk_wmem_schedule() returns false, which means no memory is allowed to allocate, it will block and wait for memory to become available. Note different from tcp, sctp wait_for_buf happens before allocating any skb, so memory accounting check is done with the whole msg_len before it too. Reported-by:

Ido Schimmel says: ==================== mlxsw: Add neighbour offload indication Neighbour entries are programmed to the device's table so that the correct destination MAC will be specified in a packet after it was routed. Despite being programmed to the device and unlike routes and FDB entries, neighbour entries are currently not marked as offloaded. This patchset changes that. Patch #1 is a preparatory patch to make sure we only mark a neighbour as offloaded in case it was successfully programmed to the device. Patch #2 sets the offload indication on neighbours. Patch #3 adds a test to verify above mentioned functionality. Patched iproute2 version that prints the offload indication is available here [1].
