I'm getting flapping on the first port of my i350-T4 which is connected directly to a Mac Mini. The other ports are not flapping nor is the WAN (which is onboard Intel on the motherboard).

Nothing in the log before it detaches. I think this has been happening for a while but it's gotten worse with the latest releases. What's the proper troubleshooting procedure in this scenario?
Swapping the cables physically between my first and second lans then reassigning the lans to the other ports seems to have worked. Is there any reason this would be the case? Maybe I should try assigning then back to the original ports and see if the process of assigning/linking them is what solved it?
