802.3ad on intel e810 not sending lacp packets

[LeonSchumacher]

Hi,
I’m seeing a reproducible issue with Talos Linux + Intel E810 (ice) NICs in a bonded 802.3ad setup where one port stops transmitting LACP entirely after the corresponding switch port is shut down for testing.
Summary

Talos kernel: 6.12.57‑talos
NIC: Intel E810‑XXV (25G)
NIC firmware: 4.51 / NVM 23.0.8
Bond mode: 802.3ad, LACP slow
Switch: Cisco ACI (vPC)

Problem

When the upstream switch port of one slave (e.g., ens3f1np1) is administratively shut, the NIC:

Continues to receive LLDP + LACP from the switch
Never transmits any LACP frames again
TX counters barely move
Bonding driver reports Actor key: 0, LACP partner defaulted
tcpdump -Q out shows zero outgoing LACP PDUs indefinitely
Other bond member works normally

The port effectively becomes RX‑only, even after the switch port comes back up.
This persists until the NIC port is fully reset.

What I’m trying to understand

Is this a known interaction between the Talos‑bundled ice driver and E810 NVM 23.x?
Does Talos require or recommend a minimum NVM bundle version for E810?
Have others seen LACP transmit failures / one‑way link behavior on Talos with E810?

Any insights or confirmation would be appreciated. Happy to provide logs or additional data.
Thanks!

Do you have ice-firmware extension installed?

[LeonSchumacher]

Yes siderolabs/intel-ice-firmware is installed on the node

What are the bond settings that you're applying?

I think you should have miimon values to make it useable at the very least.

See e.g. for an example https://docs.siderolabs.com/talos/v1.12/networking/logical/bond

[LeonSchumacher]

Okay thanks i will add the parameters and report back.
I suspect there is no default value for miimon if not set?

[smira]

yes, default value is 0.

Thank you, that was the issue, i went ahead and also set the other values given in the docs.
