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

Introduce a new option ad_actor_port_prio, allowing users to set the actor port priority on a per-port basis in LACPDU.
This priority can be used in future enhancements to influence aggregator selection via ad_select policy.

Hi Nikolay,
Is this a note for you? Or you want me add it to the doc?
Thanks Hangbin
Now that per-port actor priority is supported via ad_actor_port_prio, enable a new ad_select policy to choose the aggregator based on port priority.
This allows users to influence aggregator selection by assigning higher or lower priorities to individual ports.

Now that per-port actor priority is supported via ad_actor_port_prio, enable a new ad_select policy to choose the aggregator based on port priority.
This allows users to influence aggregator selection by assigning higher or lower priorities to individual ports.

The active aggregator is chosen by the highest total sum ofactor port priorities across its active ports. Note thispriority is ad_actor_port_prio, not per port prio, which isused for primary reselect.- The bandwidth, count and prio selection policies permit failover of 802.3ad aggregations when partial failure of the active aggregator occurs. This keeps the aggregator with the highest availability (either in bandwidth or in number of ports) active at all times.

Add a selftest to verify that per-port actor priority (ad_actor_port_prio) is correctly applied and affects aggregator selection as expected.
Move cmd_jq from forwarding/lib.sh to net/lib.sh.

Hi Jakub,
Should I drop this selftest as it needs the new iproute2 feature that has not applied yet?

Cool! Do you run CI for all posted patches?
I just found that I forgot to rebase the code to latest net-next, which will have a conflict in include/net/bond_options.h... I see your email that the net-next is closed. So I think we can just leave this patchset for reviewing. I can post the next version after net-next re-open.
Thanks Hangbin

Yes, the quick checks like shellcheck we run on individual patches, but selftests get batched. I mean we collect patches from n hours (currently 3) and test them all together.
