	Note I've also tested this on yesterday's src-6 stable & same there.


	
>Description:
	nve0: ifconfig shows a false setting of 10baseT/UTP

>How-To-Repeat:
	Connect a main board with this chip to a 100M switch, eg Netgear 100M
	Note my board belongs to a customer, on short term loan,
	if anyone has a fix or test they want me to run, best be quick please.

>Fix:

	

Document it as per appended diff.
