Hi, We have som machines with Intel i350 NICs which after upgrading from 11.2-RELEASE to 12.1-RELEASE has started to act up. They will detect link and come up initially when brought up, but they will not detect link down events when the connection is lost, e.g. if we remove the network cable. This is a big problem for us as they are used in a failover lagg which is currently not working due to this. `ifconfig <if> down ; ifconfig <if> up` does not have any effect. I cannot see anything in dmesg or any other logs. Removing the interfaces from lagg interface does not make any changes to this behaviour, nor did disabling `vlanhwtag` which I found a bug report for issues with when using these NICs. Is this a known regression from 11.X? Any advise for how to debug this further? -- Marius Halden
