When running with about 1Gbit/ses for very long time, running ifconfig
and netstat causes dead lock. These symptoms are similar to the
commit 5f6b4e14cada ("net: dsa: User per-cpu 64-bit statistics"). After
replacing network devices statistics with per-cpu 64-bit statistics,
the dead locks disappear even after very long time running with 1Gbit/sec.
Based on Eric's advice, "If the loops are ever restarted, the
storage->fields will have been modified multiple times.".
A similar change in the commit 5f6b4e14cada ("net: dsa: User per-cpu
64-bit statistics") is borrowed to fix the above problem.
