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