Hence, FW is going into DEEP SLEEP in associated state, which is incorrect. Fix: ---- Sending station delete peer notify when assoc timeout happens. Regression potential: --------------------- Ran roaming between two AP's for 20 hours and didn't see the issue. This bug is for tracking purposes only, please don't triage.
