net: dsa: User per-cpu 64-bit statistics
During testing with a background iperf pushing 1Gbit/sec worth of traffic and having both ifconfig and ethtool collect statistics, we could see quite frequent deadlocks. Convert the often accessed DSA slave network devices statistics to per-cpu 64-bit statistics to remove these deadlocks and provide fast efficient statistics updates.
