Subject: [PATCH net-next v3 0/2] net: stmmac: fix & improve driver statistics
Date: Tue, 20 Jun 2023 00:52:18 +0800 [thread overview]
Message-ID: <20230619165220.2501-1-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.
NOTE: v1 and v2 are back ported from an internal LTS tree, I made
some mistakes when backporting and squashing. Now, net-next + v3
has been well tested with 'ethtool -s' and 'ip -s link show'.
Since v2:
- fix ethtool .get_sset_count, .get_strings and per queue stats
couting.
- fix .ndo_get_stats64 only counts the last cpu's pcpu stats.
- fix typo: s/iff/if in commit msg.
- remove unnecessary if statement brackets since we have removed
one LoC.
Since v1:
- rebase on net-next
- fold two original patches into one patch
- fix issues found by lkp
- update commit msg
