FQ-PIE runs an independent PIE controller per flow but exposes no per-flow statistics. This series wires up fq_pie_class_ops to expose per-flow AQM state (prob, delay, deficit, avg_dq_rate) via 'tc -s class show', following a similar pattern as FQ-CoDel. --- Changelog:
v4: - Fixed unaligned commit message; moved typo fixes to another patch. v3: https://lore.kernel.org/netdev/[email protected]/ - No changes since v2. - Resent after the previous submission was deferred due to the net-next tree closing during review. - Updated corresponding iproute2 patch in response to review comments; kernel patches unchanged. v2: https://lore.kernel.org/netdev/[email protected]/ - Addressed ABI backward compatibility issue for tc_fq_pie_xstats. v1: https://lore.kernel.org/netdev/[email protected]/ - Initial submission Hemendra M.
