Subject: [PATCH wpan-next v3 1/6] ieee802154: Add support for user scanning requests
Date: Tue, 3 Jan 2023 17:56:39 +0100 [thread overview]
Message-ID: <20230103165644.432209-2-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20230103165644.432209-1-miquel.raynal@bootlin.com>
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.
