Why is rndis still being used?  It's an insecure and obsolete protocol
that should not be used at all anywhere.  I keep trying to delete it
entirely, but need to go and write an active exploit to prove to people
just how bad it really is before I can do so...

Adding more functionality to it is not a good idea, what is wrong with
the other, built-in, networking protocols instead?  Why are you using
this old one still when there are so many better options out there?

thanks,
