Subject: [PATCH net-next v2 0/2] net: stmmac: fix & improve driver statistics
Date: Sat, 17 Jun 2023 21:09:41 +0800	[thread overview]
Message-ID: <20230617130943.2776-1-jszhang@kernel.org> (raw)

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
