Subject: [PATCH net-next v2 0/2] Add L2 hw acceleration for airoha_eth
 driver

Introduce the capability to offload L2 traffic defining flower rules in
the PSE/PPE engine available on EN7581 SoC.
Since the hw always reports L2/L3/L4 flower rules, link all L2 rules
sharing the same L2 info (with different L3/L4 info) in the L2 subflows
list of a given L2 PPE entry.

---
Changes in v2:
- squash patch 1/3 and 2/3
- explicitly initialize airoha_flow_table_entry type for
  FLOW_TYPE_L4 entry
- get rid of airoha_ppe_foe_flow_remove_entry_locked() and just rely on
  airoha_ppe_foe_flow_remove_entry()
- Link to v1: https://lore.kernel.org/r/20250407-airoha-flowtable-l2b-v1-0-18777778e568@kernel.org
