[PATCH net-next v2 0/2] net: stmmac: fix & improve driver statistics

[Jisheng Zhang]

improve the stmmac driver statistics:

1. don't clear network driver statistics in .ndo_close() and
.ndo_open() cycle
2. avoid some network driver statistics overflow on 32 bit platforms
3. use pcpu statistics where necessary to remove frequent cacheline
ping pongs.

Since v1:
  - rebase on net-next
  - fold two original patches into one patch
  - fix issues found by lkp
  - update commit msg

  net: stmmac: don't clear network statistics in .ndo_open()
  net: stmmac: use pcpu 64 bit statistics where necessary
