[PATCH] IB/ipath: namespace cleanup: replace ips with ipath
Remove ips namespace from infinipath drivers. This renames ips_common.h to ipath_common.h. Definitions, data structures, etc. that were not used by kernel modules have moved to user-only headers. All names including ips have been renamed to ipath. Some names have had an ipath prefix added.
