From 57588c71177f0bfc08509c2c3a9bfe32850c0786 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Tue, 3 Jan 2023 17:56:44 +0100 Subject: mac802154: Handle passive scanning 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.
