mac802154: Handle passive scanning

2023-01-03T18:48:43+00:00

Implement the core hooks in order to provide the softMAC layer support for passive scans. Scans are requested by the user and can be aborted. Changing channels manually is prohibited during scans. The implementation uses a workqueue triggered at a certain interval depending on the symbol duration for the current channel and the duration order provided. More advanced drivers with internal scheduling capabilities might require additional care but there is none mainline yet. Received beacons during a passive scan are processed in a work queue and their result forwarded to the upper layer. Active scanning is not supported yet.

ieee802154: Add support for user scanning requests

2023-01-03T18:31:03+00:00

The ieee802154 layer should be able to scan a set of channels in order to look for beacons advertizing PANs. Supporting this involves adding two user commands: triggering scans and aborting scans. The user should also be notified when a new beacon is received and also upon scan termination. A scan request structure is created to list the requirements and to be accessed asynchronously when changing channels or receiving beacons. Mac layers may now implement the ->trigger_scan() and ->abort_scan() hooks.

mac802154: Introduce filtering levels

2022-10-12T10:56:28+00:00

The 802154 specification details several filtering levels in which the PHY and the MAC could be. The amount of filtering will vary if they are in promiscuous mode or in scanning mode. Otherwise they are expected to do some very basic checks, such as enforcing the frame validity. Either the PHY is able to do so, and the MAC has nothing to do, or the PHY has a lower filtering level than expected and the MAC should take over. For now we just define these levels in an enumeration. In a second time, we will add a per-PHY parameter showing the expected filtering level as well as a per device current filtering level, and will initialize all these fields. In a third time, we will use them to apply more filtering by software when the PHY is limited. Indeed, if the drivers know they cannot reach the requested level of filtering, they will overwrite the "current filtering" parameter so that it reflects what they do. Then, in the core, the expected filtering level will be used to decide whether some additional software processing is needed or not.

There are more codes than already listed, let's be a bit more exhaustive. This will allow to drop device drivers local definitions of these codes.

net: ieee802154: Enhance/fix the names of the MLME return codes

2022-04-25T18:51:12+00:00

Let's keep these definitions as close to the specification as possible while they are not yet in use. The names get slightly longer, but we gain the minor cost of being able to search the spec more easily.
