+        This is a driver that provides InfiniBand verbs support for
+        PathScale InfiniPath host channel adapters (HCAs).  This
+        allows these devices to be used with both kernel upper level
+        protocols such as IP-over-InfiniBand as well as with userspace
+        applications (in conjunction with InfiniBand userspace access).
