Add the definition of pvSCSI protocol used between the pvSCSI frontend in a
XEN domU and the pvSCSI backend in a XEN driver domain (usually Dom0).
This header was originally provided by Fujitsu for XEN based on Linux 2.6.18.

I'm using 3.10.40 kernel with adaptec 3405 and unfortunately I'm getting I/O

errors or what these actually mean?
