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: v3: - No changes since v2. - Resending as the previous submission was deferred when the net-next tree closed during review. - Corresponding iproute2 patch updated in response to review comments; no changes required for this patch. v2: - Addressed ABI backward compatibility issue for tc_fq_pie_xstats.
