Cover letter [PATCH 0/1] 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).
However, a defective NIC (very rare, fortunately) can see such an error quite often, ie. every few minutes under high load.Make the limit tunable to allow people with mission critical installations
to crank up the tunable and recover an INTMAX number of times while waiting
for a downtime window to replace the NIC. The performance won't be optimal,
but at least, it will still work.

Ok...
Then please apply the following patch which limits the number of recovery to 1 without making it tunable. It will at least enable detection of bad NICs.
