Hi mates!
Until recently, the automatic speed detection of the NIC was correct - 1000Mbit. I have been observing the following behavior for several days:
After a few hours it stops and I see this:
My box has FreeBSD 13.2-RELEASE-p4.
I have 1Gbit switch and same router. Lan cable 6th category.
Is there a way to debug interface to find the reason?

igb0
autodetect 1Gbit speed and same situation does repeat again.
