Date: Mon, 11 Jun 2007 20:26:31 +0200 From: Brice Goglin <brice@...i.com> To: Jeff Garzik <jeff@...zik.org> CC: netdev@...r.kernel.org Subject: [PATCH 1/3] myri10ge: limit the number of recoveries Limit the number of recoveries from a NIC hw watchdog reset to 1 by default. It enables detection of defective NICs immediately since these memory parity errors are expected to happen very rarely (less than once per century*NIC).
