Date: Mon, 07 May 2007 23:51:10 +0200 From: Brice Goglin <brice@...i.com> To: Jeff Garzik <jeff@...zik.org> CC: netdev@...r.kernel.org Subject: [PATCH 4/6] myri10ge: limit the number of recoveries Limit the number of recoveries from a NIC hw watchdog reset to 1 by default. This is tweakable via the myri10ge_reset_recover tunable.
