We are currently accepting bug fixes only. Please repost when net-next reopens after July 10th. RFC patches sent for review only are obviously welcome at any time. See: https://www.kernel.org/doc/html/next/process/maintainer-netdev.html#development-cycle
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 per-queue 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 v3: - coding style pointed out by Simon, I.E reverse xmas tree for local variable declarations and so on. - put the counters in queue structs, I.E per-queue rather than per-cpu - use _irqsave() variant where necessary. 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 Jisheng Zhang (2): net: stmmac: don't clear network statistics in .ndo_open() net: stmmac: use per-queue 64 bit statistics where necessary drivers/net/ethernet/stmicro/stmmac/common.h | 39 ++-- .../net/ethernet/stmicro/stmmac/dwmac-sun8i.c | 12 +- .../ethernet/stmicro/stmmac/dwmac100_dma.c | 7 +- .../ethernet/stmicro/stmmac/dwmac4_descs.c | 16 +- .../net/ethernet/stmicro/stmmac/dwmac4_lib.c | 15 +- .../net/ethernet/stmicro/stmmac/dwmac_lib.c | 12 +- .../ethernet/stmicro/stmmac/dwxgmac2_descs.c | 6 +- .../ethernet/stmicro/stmmac/dwxgmac2_dma.c | 14 +- .../net/ethernet/stmicro/stmmac/enh_desc.c | 20 +- drivers/net/ethernet/stmicro/stmmac/hwif.h | 12 +- .../net/ethernet/stmicro/stmmac/norm_desc.c | 15 +- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 2 + .../ethernet/stmicro/stmmac/stmmac_ethtool.c | 123 ++++++++--- .../net/ethernet/stmicro/stmmac/stmmac_main.c | 206 ++++++++++++++---- 14 files changed, 337 insertions(+), 162 deletions(-)
