MOST network protocol

This patch set includes known-working code, developed by Wind River and Intel, published at http://sourceforge.net/projects/sta2x11/ .

We fixed a number of things in the code, porting to the current linux-next and upstream sta2x11 code, factorizing replicated code, making stuff more readable and fixing buglets. (We is Federico Vaga, Alessandro Rubini, Giancarlo Asnaghi).

Patch 1 is the core, patch 2 is an interface driver and patch 3 is a pci fixup in the chipset that hosts the logic block for the interface.

Unfortunately, the code implements network-specific system calls but doesn't fit in the kernel network subsystem. Instead of using skbuffs and network interfaces, it sets up a direct connection between the system calls and custom-defined operations for the hardware driver.

We are aware patch 1/3 and 2/3 cannot be merged without serious refactoring, and for this reason we are not adding signed-off-by markers.

Still, we think the current code may be useful to other people
nonetheless: the MOST protocol is not very common, but it is not an exotic single-vendor thing, either.

We plan to work on resubmitting this in the upcoming months, adapting to the proper conventions for a network protocol.
