X710 NIC throughput issues after 24 hours after auto-negotiation

[RBeer5]

I have a few X710 NIC that after upgrading to the latest firmware they start to exhibit throughput issues after roughly 24 hours. We resolve the issue by flapping the port which resolves the issue for another 24 hours.

We have many of these devices in a Dell M1000e M630 blade servers and the only two servers with the issue have the latest firmware:

ethtool -i em1 driver: i40e version: 2.9.21 firmware-version: 7.10 0x800051a0 19.0.12 expansion-rom-version: bus-info: 0000:01:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes

The firmware and driver are those available via Dell.

As this is a blade server and there is a pass-through module I am unable to switch off auto-neg on the network card.

With this firmware release I am not able to roll back to an earlier version which I know works without issue.

Can anyone help identify the issue?
