From f181137f9d70dc851dcb418cdad4df7888a0bfd3 Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Mon, 11 Jun 2007 20:26:31 +0200 Subject: [PATCH] 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).
