Subject: [PATCH V2 08/11] net: mediatek: increase watchdog_timeo
Date: Fri, 10 Jun 2016 13:28:05 +0200 [thread overview]
Message-ID: <1465558088-15265-9-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1465558088-15265-1-git-send-email-john@phrozen.org>
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.
