patch1 and patch2 fix two issues in net driver statistics:
1. network driver statistics are cleared in .ndo_close() and
.ndo_open() cycle
2. some network driver statistics overflow on 32 bit platforms

patch3 use pcpu statistics where necessary to remove frequent
cacheline ping pongs.

Jisheng Zhang (3):
  net: stmmac: don't clear network statistics in .ndo_open()
  net: stmmac: fix overflow of some network statistics
  net: stmmac: use pcpu statistics where necessary
