<rk> I have made changes and done some basic testing which includes "1"
port only. Getting more than 2 ports is a bit taxing to me as I am an
individual  contributor and wanted to find a way to test with what I had. I
have made additional changes esp. handling cases to avoid error messages
seen in "dts.log" . Do you want me to send a patch to you along with
support added for I217 and i218?

<rk> Issue here was more delay needed for I217 ports to acquire v6
addresses after link up. If you are ok I can send a patch for this.

Thanks,
