Subject: Re: Is this 32-bit NCM?

Here are two USB captures.
In m1 - the computer is "silent": and it can listen to ARP traffic coming from 
the modem.
In m2, the computer tries to talk, performing DHCP with dhclient from Ubuntu.
Any strange thing?
Is the device really interpreting ndpOffset as Offset in the specs Kevin?
If so we might elaborate on this.
