Subject: [PATCH net-next v2 0/9] net: stats, tools, driver tests for HW GRO

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
