From fbc1cc6973099f45e4c30b86f12b4435c7cb7d24 Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Tue, 28 Oct 2025 12:58:40 +0200 Subject: wifi: mac80211: use wiphy_hrtimer_work for csa.switch_work The work item may be scheduled relatively far in the future. As the event happens at a specific point in time, the normal timer accuracy is not sufficient in that case. Switch to use wiphy_hrtimer_work so that the accuracy is sufficient. To make this work, use the same clock to store the timestamp.
