-Subject: [PATCH 2/2] wifi: rtl8xxxu: enable channel switch support
-
-The CSA countdown in the beacon frames, which are sent out by firmware,
-needs to get updated by the driver. To achieve this, convert
-update_beacon_work to delayed_work and schedule it with the beacon
-interval in case CSA is active and the countdown is not complete.
