Subject[PATCH 37 of 39] IB/ipath - namespace cleanup: replace ips with ipath
Date
From
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.
