This is a port of i40e commit 70563957 ("i40e: need_wakeup flag might not be set for Tx"). Quoting the original commit message: "The need_wakeup flag for Tx might not be set for AF_XDP sockets that are only used to send packets. This happens if there is at least one outstanding packet that has not been completed by the hardware and we get that corresponding completion (which will not generate an interrupt since interrupts are disabled in the napi poll loop) between the time we stopped processing the Tx completions and interrupts are enabled again. In this case, the need_wakeup flag will have been cleared at the end of the Tx completion processing as we believe we will get an interrupt from the outstanding completion at a later point in time. But if this completion interrupt occurs before interrupts are enable, we lose it and should at that point really have set the need_wakeup flag since there are no more outstanding completions that can generate an interrupt to continue the processing. When this happens, user space will see a Tx queue need_wakeup of 0 and skip issuing a syscall, which means will never get into the Tx processing again and we have a deadlock." As a result, packet processing stops. This patch introduces a fix for this issue, by always setting the need_wakeup flag at the end of an interrupt processing. This ensures that the deadlock will not happen.

Distribute the Tx queues evenly across all queue groups. This will help the queues to get more equal sharing among the queues when all are in use. In the previous algorithm, the next queue group node will be picked up only after the previous one filled with max children. For example: if VSI is configured with 9 queues, the first 8 queues will be assigned to queue group 1 and the 9th queue will be assigned to queue group 2. The 2 queue groups split the bandwidth between them equally (50:50). The first queue group node will share the 50% bandwidth with all of its children (8 queues). And the second queue group node will share the entire 50% bandwidth with its only children. The new algorithm will fix this issue.

The VSI rebuild could happen as a result of a user setting the number of queues via the 'ethtool -L' command.

During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability register will be cleared. This can lead to issues when a VF is assigned to a VM because in these cases the VF driver receives no indication of the PF PCI error/reset and additionally it is incapable of restoring the cleared flag in the hypervisor configuration space without fully reinitializing the driver interrupt functionality. Since the VF driver is unable to easily resolve this condition on its own, restore the VF MSI-X flag during the PF PCI reset handling.

When the driver experiences a link event (especially link up) there can be multiple events generated. Some of these are link fault and still have a state of DOWN set. The problem happens when the link comes UP during the PF driver handling one of the LINK DOWN events. The status of the link is updated and is now seen as UP, so when the actual LINK UP event comes, the port information has already been updated to be seen as UP, even though none of the UP activities have been completed. After the link information has been updated in the link handler and evaluated for MEDIA PRESENT, if the state of the link has been changed to UP, treat the DOWN event as an UP event since the link is now UP.

After a GLOBR, the link was broken so that a link up situation was being seen as a link down. The problem was that the rebuild process was updating the port_info link status without doing any of the other things that need to be done when link changes. This was causing the port_info struct to have current "UP" information so that any further UP interrupts were skipped as redundant. The rebuild flow should *not* be updating the port_info struct link information, so eliminate this and leave it to the link event handling code.

Alter the rtl8366_vlan_add() to call rtl8366_set_vlan() inside the loop that goes over all VIDs since we now properly support calling that function more than once. Augment the loop to postincrement as this is more intuitive. The loop moved past the last VID but called rtl8366_set_vlan() with the port number instead of the VID, assuming a 1-to-1 correspondence between ports and VIDs. This was also a bug.

The RTL8366 would not handle adding new members (ports) to a VLAN: the code assumed that ->port_vlan_add() was only called once for a single port. When intializing the switch with .configure_vlan_while_not_filtering set to true, the function is called numerous times for adding all ports to VLAN1, which was something the code could not handle. Alter rtl8366_set_vlan() to just |= new members and untagged flags to 4k and MC VLAN table entries alike. This makes it possible to just add new ports to a VLAN. Put in some helpful debug code that can be used to find any further bugs here.

Jacob Keller says: ==================== introduce PLDM firmware update library This series goal is to enable support for updating the ice hardware flash using the devlink flash command. The ice firmware update files are distributed using the file format described by the "PLDM for Firmware Update" standard: https://www.dmtf.org/documents/pmci/pldm-firmware-update-specification-100 Because this file format is standard, this series introduces a new library that handles the generic logic for parsing the PLDM file header. The library uses a design that is very similar to the Mellanox mlxfw module. That is, a simple ops table is setup and device drivers instantiate an instance of the pldmfw library with the device specific operations. Doing so allows for each device to implement the low level behavior for how to interact with its firmware. This series includes the library and an implementation for the ice hardware. I've removed all of the parameters, and the proposed changes to support overwrite mode. I'll be working on the overwrite mask suggestion from Jakub as a follow-up series. Because the PLDM file format is a standard and not something that is specific to the Intel hardware, I opted to place this update library in lib/pldmfw. I should note that while I tried to make the library generic, it does not attempt to mimic the complete "Update Agent" as defined in the standard. This is mostly due to the fact that the actual interfaces exposed to software for the ice hardware would not allow this. This series depends on some work just recently and is based on top of the patch series sent by Tony published at: https://lore.kernel.org/netdev/20200723234720.1547308-1-anthony.l.nguyen@intel.com/T/#t Changes since v2 RFC * Removed overwrite mode patches, as this can become a follow up series with a separate discussion * Fixed a minor bug in the pldm_timestamp structure not being packed. * Dropped Cc for other driver maintainers, as this series no longer includes changes to the core flash update command. * Re-ordered patches slightly. Changes since v1 RFC * Removed the "allow_downgrade_on_flash_update" parameter. Instead, the driver will always attempt to flash the device, even when firmware indicates that it would be a downgrade. A dev_warn is used to indicate when this occurs. * Removed the "ignore_pending_flash_update". Instead, the driver will always check for and cancel any previous pending update. A devlink flash status message will be sent when this cancellation occurs. * Removed the "reset_after_flash_update" parameter. This will instead be implemented as part of a devlink reset interface, work left for a future change. * Replaced the "flash_update_preservation_level" parameter with a new "overwrite" mode attribute on the flash update command. For ice, this mode will select the preservation level. For all other drivers, I modified them to check that the mode is "OVERWRITE_NOTHING", and have Cc'd the maintainers to get their input. ==================== Signed-off-by: David S.

Use the newly added pldmfw library to implement device flash update for the Intel ice networking device driver. This support uses the devlink flash update interface. The main parts of the flash include the Option ROM, the netlist module, and the main NVM data. The PLDM firmware file contains modules for each of these components. Using the pldmfw library, the provided firmware file will be scanned for the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for the main NVM module containing the primary device firmware, and "fw.netlist" containing the netlist module. The flash is separated into two banks, the active bank containing the running firmware, and the inactive bank which we use for update. Each module is updated in a staged process. First, the inactive bank is erased, preparing the device for update. Second, the contents of the component are copied to the inactive portion of the flash. After all components are updated, the driver signals the device to switch the active bank during the next EMP reset (which would usually occur during the next reboot). Although the firmware AdminQ interface does report an immediate status for each command, the NVM erase and NVM write commands receive status asynchronously. The driver must not continue writing until previous erase and write commands have finished. The real status of the NVM commands is returned over the receive AdminQ. Implement a simple interface that uses a wait queue so that the main update thread can sleep until the completion status is reported by firmware. For erasing the inactive banks, this can take quite a while in practice. To help visualize the process to the devlink application and other applications based on the devlink netlink interface, status is reported via the devlink_flash_update_status_notify. While we do report status after each 4k block when writing, there is no real status we can report during erasing. We simply must wait for the complete module erasure to finish. With this implementation, basic flash update for the ice hardware is supported. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The pldmfw library is used to implement common logic needed to flash devices based on firmware files using the format described by the PLDM for Firmware Update standard. This library consists of logic to parse the PLDM file format from a firmware file object, as well as common logic for sending the relevant PLDM header data to the device firmware. A simple ops table is provided so that device drivers can implement device specific hardware interactions while keeping the common logic to the pldmfw library. This library will be used by the Intel ice networking driver as part of implementing device flash update via devlink. The library aims to be vendor and device agnostic. For this reason, it has been placed in lib/pldmfw, in the hopes that other devices which use the PLDM firmware file format may benefit from it in the future. However, do note that not all features defined in the PLDM standard have been implemented. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
