+Subject: [PATCH 089/102] net-next: mediatek: increase watchdog_timeo
+
+During stress testing, after reducing the threshold value, we have seen
+TX timeouts that were caused by the watchdog_timeo value being too low.
+Increase the value to 5 * HZ which is a value commonly used by many other
+drivers.
