Module Name:    src
Committed By:   oster

Modified Files:
        src/sys/dev/raidframe: rf_desc.h rf_driver.c rf_driver.h
            rf_netbsdkintf.c rf_states.c

Log Message:
On an idea from Thor (tls@), do not fail a component if doing so would
render the RAID set completely dead.  Instead, we retry the IO a
maximum of RF_RETRY_THRESHOLD times (currently '5'), and then just
return an IO error if the IO fails.  This should reduce the damage
caused by having multiple disks appear to fail when the culprit is
really something else (power, controllers, etc.)
