Subject: [PATCH net-next v2 0/3] net: airoha: Add per-flow stats support to
 hw flowtable offloading

Introduce per-flow stats accounting to the flowtable hw offload in the
airoha_eth driver. Flow stats are split in the PPE and NPU modules:
- PPE: accounts for high 32bit of per-flow stats
- NPU: accounts for low 32bit of per-flow stats

---
Changes in v2:
- fix memory leaks in airoha_npu_stats_setup() and in
  airoha_npu_foe_commit_entry()
- disable hw keepalive
- fix sparse warnings
- Link to v1: https://lore.kernel.org/r/20250514-airoha-en7581-flowstats-v1-0-c00ede12a2ca@kernel.org
