This type is used for traps that trap control packets such as ARP request and IGMP query to the CPU.

2020-06-01devlink: Add 'mirror' trap actionIdo Schimmel1-0/+2
The action is used by control traps such as IGMP query. The packet is flooded by the device, but also trapped to the CPU in order for the software bridge to mark the receiving port as a multicast router port. Such packets are marked with 'skb->offload_fwd_mark = 1' in order to prevent the software bridge from flooding them again.

In order for DEVLINK_CMD_REGION_NEW to work for a region, the new ".snapshot" operation must be implemented in the region's ops structure. The desired snapshot id must be provided. This helps avoid confusion on the purpose of DEVLINK_CMD_REGION_NEW, and keeps the API simpler. The requested id will be inserted into the xarray tracking the number of snapshots using each id. If this id is already used by another snapshot on any region, an error will be returned.

2020-03-21ice: add basic handler for devlink .info_getJacob Keller2-0/+68
The devlink .info_get callback allows the driver to report detailed version information. The following devlink versions are reported with this initial implementation: "fw.mgmt" -> The version of the firmware that controls PHY, link, etc "fw.mgmt.api" -> API version of interface exposed over the AdminQ "fw.mgmt.build" -> Unique build id of the source for the management fw "fw.undi" -> Version of the Option ROM containing the UEFI driver "fw.psid.api" -> Version of the NVM image format. "fw.bundle_id" -> Unique identifier for the combined flash image. "fw.app.name" -> The name of the active DDP package. "fw.app" -> The version of the active DDP package. With this, devlink dev info can report at least as much information as is reported by ETHTOOL_GDRVINFO.

The devlink trigger command does not exist. While rewriting the documentation for devlink into the reStructuredText format, documentation for the trigger command was accidentally merged in. This occurred because the author was also working on a potential extension to devlink regions which included this trigger command, and accidentally squashed the documentation incorrectly. Further review eventually settled on using the previously unused "new" command instead of creating a new trigger command. Fix this by removing mention of the trigger command from the documentation.

2020-01-10devlink: convert driver-specific files to reStructuredTextJacob Keller13-68/+220
Several drivers document what parameters they support in a devlink-params-*.txt file. This file is supposed to contain both the list of generic parameters implemented by the driver, as well as a list of driver-specific parameters and their descriptions. It would also be good if the driver documentation included other driver-specific implementations, such as info versions, devlink regions, and so forth. Convert all of these documentation files to reStructuredText, and rename them to just the driver name. Future changes will include other driver-specific implementations. Each file will contain a table for the generic parameters implemented, as well as a separate table for the driver-specific parameters. Future sections such as for devlink info versions will be added to these files. This avoids creating additional devlink-<feature>-<driver> files for each devlink feature, reducing clutter in the documentation folder.
