netdevsim: Add devlink resource for nexthops

2020-11-06T19:28:50Z

The Spectrum ASIC has a dedicated table where nexthops (i.e., adjacency entries) are populated. The size of this table can be controlled via devlink-resource. Add such a resource to netdevsim so that its occupancy will reflect the number of nexthop objects currently programmed to the device. By limiting the size of the resource, error paths could be exercised and tested. Example output: # devlink resource show netdevsim/netdevsim10 netdevsim/netdevsim10: name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none resources: name fib size unlimited occ 4 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none name fib-rules size unlimited occ 3 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none name IPv6 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none resources: name fib size unlimited occ 1 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none name fib-rules size unlimited occ 2 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none name nexthops size unlimited occ 0 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables none Signed-off-by: Ido Schimmel Signed-off-by: Jakub Kicinski

ice: docs fix a devlink info that broke a table

Changeset 410d06879c01 ("ice: add the DDP Track ID to devlink info") added description for a new devlink field, but forgot to add one of its columns, causing it to break: .../Documentation/networking/devlink/ice.rst:15: WARNING: Error parsing content block for the "list-table" directive: uniform two-level bullet list expected, but row 11 does not contain the same number of items as row 1 (3 vs 4). .. list-table:: devlink info versions implemented :widths: 5 5 5 90 ... * - ``fw.app.bundle_id`` - 0xc0000001 - Unique identifier for the DDP package loaded in the device.

ice: add the DDP Track ID to devlink info

2020-10-09T20:14:19Z

Add "fw.app.bundle_id" to display the DDP Track ID of the active DDP package. This id is similar to "fw.bundle_id" and is a unique identifier for the DDP package that is loaded in the device. Each new DDP has a unique Track ID generated for it, and the ID can be used to identify and track the DDP package. Add documentation for the new devlink info version.

devlink: Add enable_remote_dev_reset generic parameter

2020-10-09T19:06:53Z

The enable_remote_dev_reset devlink param flags that the host admin allows device resets that can be initiated by other hosts. This parameter is useful for setups where a device is shared by different hosts, such as multi-host setup. Once the user set this parameter to false, the driver should NACK any attempt to reset the device while the driver is loaded.

devlink: add parser error drop packet traps

2020-10-02T23:31:55Z

Add parser error drop packet traps, so that capable device driver could register them with devlink. The new packet trap group holds any drops of packets which were marked by the device as erroneous during header parsing. Add documentation for every added packet trap and packet trap group.

ice: add support for flash update overwrite mask

2020-09-26T00:20:57Z

Support the recently added DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK parameter in the ice flash update handler. Convert the overwrite mask bitfield into the appropriate preservation level used by the firmware when updating. Because there is no equivalent preservation level for overwriting only identifiers, this combination is rejected by the driver as not supported with an appropriate extended ACK message.

devlink: introduce flash update overwrite mask

2020-09-26T00:20:57Z

Sections of device flash may contain settings or device identifying information. When performing a flash update, it is generally expected that these settings and identifiers are not overwritten. However, it may sometimes be useful to allow overwriting these fields when performing a flash update. Some examples include, 1) customizing the initial device config on first programming, such as overwriting default device identifying information, or 2) reverting a device configuration to known good state provided in the new firmware image, or 3) in case it is suspected that current firmware logic for managing the preservation of fields during an update is broken. Although some devices are able to completely separate these types of settings and fields into separate components, this is not true for all hardware. To support controlling this behavior, a new DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK is defined. This is an nla_bitfield32 which will define what subset of fields in a component should be overwritten during an update. If no bits are specified, or of the overwrite mask is not provided, then an update should not overwrite anything, and should maintain the settings and identifiers as they are in the previous image. If the overwrite mask has the DEVLINK_FLASH_OVERWRITE_SETTINGS bit set, then the device should be configured to overwrite any of the settings in the requested component with settings found in the provided image. Similarly, if the DEVLINK_FLASH_OVERWRITE_IDENTIFIERS bit is set, the device should be configured to overwrite any device identifiers in the requested component with the identifiers from the image. Multiple overwrite modes may be combined to indicate that a combination of the set of fields that should be overwritten. Drivers which support the new overwrite mask must set the DEVLINK_SUPPORT_FLASH_UPDATE_OVERWRITE_MASK in the supported_flash_update_params field of their devlink_ops.
