axe(4) requires correct resolved speed/link status reported from
PHY driver. Otherwise it will incorrectly reprogram some registers
and this can result in unexpected result.
The OUI 0x1e from the above looks odd and I'm not aware of any PHY
vendors that reports such OUI. Because FreeBSD does not strictly
follows OUI decoding defined by IEEE it's also possible that
FreeBSD incorrectly showed wrong OUI. What is your USB ethernet
controller model?

Unless we fix the PHY issue you would get the same result on
stable/8.

I have no experience with usb200m so I don't know.
