Subject: [PATCH net-next 0/3] bonding: support aggregator selection based on port priority

This patchset introduces a new per-port bonding option: `ad_actor_port_prio`.

It allows users to configure the actor's port priority, which can then be used
by the bonding driver for aggregator selection based on port priority.

This provides finer control over LACP aggregator choice, especially in setups
with multiple eligible aggregators over 2 switches.

Hangbin Liu (3):
  bonding: add support for per-port LACP actor priority
  bonding: support aggregator selection based on port priority
  selftests: bonding: add test for LACP actor port priority
