Subject: [PATCH net-next v2 0/2] net/sched: sch_fq_pie: add per-flow class statistics
Date: Sun, 14 Jun 2026 18:19:58 +0530 [thread overview]
Message-ID: <20260614125000.6058-1-hemendranaik@gmail.com> (raw)
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:
v2: Addressed ABI backward compatibility issue for tc_fq_pie_xstats.
v1: https://lore.kernel.org/netdev/20260531125314.22492-1-hemendranaik@gmail.com/
