USB-IP patches

Here's 3 patches that adds USB-IP functionality code to the kernel tree.

It is against 2.6.27-rc4, and has been added to the -staging tree. If there are no major objections, I'll also queue it up in the usb tree for submission into 2.6.28.

The code is based on Takahiro's great work that has been sitting outside of the kernel for many many years now. Brian Merrell took the most recent version of the code, cleaned it up and sent it to me. I did more cleanup and split the patch into 3 pieces, making it a bit easier to work with.

There are still a number of checkpatch.pl warnings/errors emitted, and Brian said he would work on them in the upcoming weeks, but they don't distract from the basic functionality and a good review would be nice to have.

We do need some more documentation for how to use this code (you need the tools at usbip.sf.net), and how the sysfs files are exporting data to userspace. Brian, can you write up the sysfs interface in the format that Documentation/ABI/ details and also provide some kind of basic HOWTO to include in the kernel source tree?

thanks,
