I'm having issues with an Intel E810-XXV card on a Dell server under Ubuntu Jammy.

Details:

- hardware --> a1:00.0 Ethernet controller: Intel Corporation Ethernet Controller E810-XXV for SFP (rev 02)

- tested with both GA and HWE kernels (`5.15.0-83-generic #92` and `6.2.0-32-generic #32~22.04.1-Ubuntu`) with the same results.

- using a bond over the two ports of the same card, at 25Gbps to two different switches, bond is using LACP with hash layer3+4 and fast timeout. But I believe the bug is not directly related to bonding as the problem seems to be in the interface.

- machine installed by maas. No issues during installation, but at that time bond is not formed yet, later when linux is booted, the bond is formed and works without issues for a while

- it works for about 2 to 3 hours fine, then the issue starts (may or may not be related to network load, but it seems that it is triggered by some tests that I run after openstack finishes installing)

- one of the legs of the bond freezes and everything that would go to that lag is discarded, in and out, ping to random external hosts start losing every second packet

- after some time you can see on the kernel log messages about "NETDEV WATCHDOG: enp161s0f0 (ice): transmit queue 166 timed out" and a stack trace

- the switch does log that the bond is flapping
