bridge: 64bit rx/tx counters
Use u64_stats_sync infrastructure to provide 64bit rx/tx counters even on 32bit hosts. It is safe to use a single u64_stats_sync for rx and tx, because BH is disabled on both, and we use per_cpu data. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
