Limit the number of recoveries from a NIC hw watchdog reset to 1 by

It enables detection of defective NICs immediately since these memory

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.

NAK.

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.
