Bug#892105: i40e

[Mikhail Krylatykh <mikhail.krylatykh@skyeng.ru>]

We have the same problem here with the newest Stretch 4.9 kernel. When using a secondary IP address the i40e driver starts to randomly ignore ARP requests and makes the system unreachable for the rest of the network.

Upgrading to a backport kernel (4.19) with newer 4.19 driver fixes the problem.

Hi,

We've faced the same issue with Debian Stretch. i40e driver with version 1.6.16 silently dropped ARP packets while not `promisc on` enabled on target interface. Update to linux-image-4.19 from backports (i40e driver comes with version 2.3.2) repository fixed this issue.

Thanks for comments and suggested workaround.
