Another point of interest with these NICs.  The one that is connected to 
the Nokia ONT XS-010X-Q stops functioning at random times, usually days 
apart.  The interface shows it as up and the ONT looks like it is happy 
and even blinks showing data is flowing (in at least one direction), but 
the only packets I see on the NIC are ARP requests for the upstream 
router.

The other two NICs have not shown this issue.

The resolution is to either bring the NIC down then up or merely 
changing the options on the NIC.  This makes me suspect it is the NIC at 
fault but unsure if it is the driver or this particular NIC.  I guess I 
can swap the NICs around to see if the problem resolves itself or 
follows the NIC.

One other thing to point out is that this ONT is new, so it could still 
be the faulty bit.
