cxgb3: Fix EEH final recovery attempt
EEH attempts to recover up 6 times. The last attempt leaves all the ports and adapter down.hen The driver is then unloaded, bringing the adapter down again unconditionally. The unload will hang. Check if the adapter is already down before trying to bring it down again. Signed-off-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
