Looks like good progress...

Did you make sure to set both ends of the link up in compatible
ways ... like being the only two hosts on 192.168.4.* and with
netmask 255.255.255.0?  (Or something similar, not necessarily
using a /8 subnet.)

As a rule, when I hook up a link and it doesn't behave, that's
exactly what's wrong.  I've not yet gotten around to making
ZCIP automate everything.

OK, so far so good.  Looks like you're talking RNDIS to
the host, no disagreements there any more.

Do you know why it entered promiscuous mode?  Is
that something you did ... like start "tcpdump"?

OK, at this point the host expects to be able to talk to you.
Packets _should_ flow just fine on the link.  Which is just
what they did for me, and I don't want to assume I was just
lucky or anything ... :)

I don't know enough RNDIS to figure out whether any of this
traffic reflects a confused host, but my initial impression
is that RNDIS is just chatty.
