Increase the value to 5 * HZ which is a value commonly used by many other

I've never studied what watchdog_timeo actually means. Does it mean a
transmit has not completed in that amount of time? Would this imply
you have 5 seconds worth of packets in your transmit queue? Do you
know what the driver is doing during this 5 seconds?
