Have you swapped hardware yet?
Hopefully I'm not spreading fud but didn't the I226-V NIC's have stability issues with FreeBSD?

So that's a fairly new chipset. Even Intel itself only has windows drivers:https://www.intel.com/content/www/us/en/products/sku/210599/intel-ethernet-controller-i226v/downloads.htmlSo if BSD does support them, it's on it's own within the kernel. I would question this greatly.
