get_stats() method incorrectly clears a global array before folding various stats. This can break SNMP applications. Switch to 64 bit flavor to work on a user supplied buffer, and provide 64bit counters even on 32bit arches. Fix a bug in bnad_netdev_hwstats_fill(), for rx_fifo_errors, missing a folding (only the last counter was taken into account) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.
