This series adds tc support for printing per-flow statistics via 'tc -s class show', matching the kernel fq_pie class ops series. The corresponding kernel series can be viewed here: https://lore.kernel.org/netdev/20260928043358.6866-1-hemendranaik@gmail.com/ Both the kernel and iproute2 patches can also be found in GitHub: - https://github.com/H-N41K/linux-net-next/tree/fq_pie_class_stats/ - https://github.com/H-N41K/iproute2-next/tree/fq_pie_class_stats/ --- Changelog: v8: - No code changes since v7. - Rebased and reposted patch since corresponding kernel series was reposted. v7: https://lore.kernel.org/all/20260922211139.38570-1-hemendranaik@gmail.com/ - Removed UAPI header changes. The series now contains 2 commits. v6: https://lore.kernel.org/netdev/20260919061254.39678-1-hemendranaik@gmail.com/ - No code changes since v5. - Rebased over the latest iproute2-next tree and re-submitted patch. v5: https://lore.kernel.org/netdev/20260902040221.83734-1-hemendranaik@gmail.com/ - Addressed Sashiko review comments (folded into patch 1/3): - Dropped empty tc_fq_pie_xqd_stats placeholder; class_stats is now a direct struct member in the UAPI header. v4: https://lore.kernel.org/netdev/20260727165028.106817-1-hemendranaik@gmail.com/ - Split into 3 patches: fq_pie class stats, pie avg_dq_rate formatting, and tc_pie_xstats comment fixes. v3: https://lore.kernel.org/netdev/20260630184453.171410-1-hemendranaik@gmail.com/ - Moved print_nl() into each xstats type block to preserve output formatting. v2: https://lore.kernel.org/netdev/20260614130729.10076-1-hemendranaik@gmail.com/ - Addressed ABI backward compatibility issue. v1: https://lore.kernel.org/netdev/20260531131411.28213-1-hemendranaik@gmail.com/ - Initial submission Hemendra M.
