Then stop coexistence TX after HCI unregister and before USB reset or SDIO chip reset and function disable. Probe failures are covered before buffer freeing or function disable. Patch 1 makes repeated thread stops safe and prevents the WLAN TX loop from draining queued packets after a stop request. Patch 2 does the same for coexistence TX without adding an exported core-to-bus wrapper. The driver is orphaned and the series was not run on RS9113 or RS9116 hardware. Testing from device users would be helpful. LLM assistance was used to review this series.
