Hi, Emil
Thanks for your quick reply. I can not reproduce this problem because I have no such i40e nic. But from the log: " ... [ 211.955239] i40e 0000:04:00.0 enp4s0f0: speed changed to 0 for port enp4s0f0 [ 211.956912] bond0: link status up again after 0 ms for interface enp4s0f0 ... " And the user made tests with the command "ethtool -r". That is, "ethtool -r" can resolve this problem. According to the above, I think the root cause is that link_speed and link_up do not synchronize. It is similar to the ixgbe and bonding. Wait for your comments. Best Regards!
