Subject: [PATCH net-next v2 0/9] net: stats, tools, driver tests for HW GRO
Date: Fri, 6 Feb 2026 16:35:00 -0800 [thread overview]
Message-ID: <20260207003509.3927744-1-kuba@kernel.org> (raw)
Add miscellaneous pieces related to production use of HW-GRO:
- report standard stats from drivers (bnxt included here,
Gal recently posted patches for mlx5 which is great)
- CLI tool for calculating HW GRO savings / effectiveness
- tests for the stats, packet ordering and depth
v2:
- [patch 1] fix ethtool -S and unnecessary feature check
- [patch 3] use %1$s
- [patch 6] do not enable SO_TXTIME for multi-flow tests
- [patch 9] move the test to cover SW GRO
v1: https://lore.kernel.org/20260205220541.2992807-1-kuba@kernel.org
Jakub Kicinski (9):
eth: bnxt: gather and report HW-GRO stats
tools: ynltool: factor out qstat dumping
tools: ynltool: add qstats analysis for HW-GRO efficiency / savings
selftests: net: move gro to lib for HW vs SW reuse
selftests: drv-net: give HW stats sync time extra 25% of margin
selftests: drv-net: gro: use SO_TXTIME to schedule packets together
selftests: drv-net: gro: test GRO stats
selftests: drv-net: gro: add test for packet ordering
selftests: drv-net: gro: add a test for GRO depth
