Add some simple script which creates a USB gadget using ConfigFS
and then exports it using vUDC.
This may be useful for people who just started playing with
USB/IP and vUDC as it shows exact steps how to setup all stuff.

Looks like it also includes client side, would it make sense to not name is server
and call it vudc_export_example.sh?

This is the first file under usbip with a different license. Why did you chose
this over GPL that is what is in all oter source files in this module?

This script is intended to be run on a server side not on client or
both. It contains only couple of comments with suggestion what you
should do on a client side but any of those commands won't be executed
as the are all placed inside comments.
Moreover, our goal while developing vUDC was to make it compatible with
existing USB/IP infrastructure. That's why client side usage is pretty
the same for both vUDC and stub driver.

The reason is very simple. It's just an *example* of vUDC usage, nothing
more. There is no new or useful functionality inside this script so I
don't see any reason to guard it with GPL license.
As far as I'm familiar with this license (please correct me if I'm
wrong), it simply allows everyone to use this script as their code base
and modify it to fit their needs and put them into products without
publishing the code. Which I think may be useful for some people.

Hmm... true. Usually I just simply build in this module in my test setup
and that's why I forgot about it;)
I'll add this in next version.
