Subject: [PATCH 1/3] pch_gbe: fix transmit watchdog timeout
Date: Thu, 26 Jul 2012 11:59:07 -0400 [thread overview]
Message-ID: <20120726155907.GB10287@telcoserv5> (raw)
An extended ping test with 6 vlans resulted in a driver oops with a
netdev transmit timeout.
Fix WATCHDOG_TIMEOUT to be more like e1000e at 5 * HZ, to avoid
unnecessary transmit timeouts.
