From 6241d79f0043298e30679535472a8498d99161b0 Mon Sep 17 00:00:00 2001 From: Aditya Kumar Singh Date: Fri, 6 Sep 2024 12:14:19 +0530 Subject: Revert "wifi: mac80211: move radar detect work to sdata" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit ce9e660ef32e ("wifi: mac80211: move radar detect work to sdata"). To enable radar detection with MLO, it’s essential to handle it on a per-link basis. This is because when using MLO, multiple links may already be active and beaconing. In this scenario, another link should be able to initiate a radar detection. Also, if underlying links are associated with different hardware devices but grouped together for MLO, they could potentially start radar detection simultaneously. Therefore, it makes sense to manage radar detection settings separately for each link by moving them back to a per-link data structure.
